Executive Summary: A Deal Remains ElusiveIran’s leadership has not ruled out a settlement with the United States, but competing hawkish voices on both sides are raising demands that keep any understanding out of reach. The war‑driven environment, disputes over the Strait of Hormuz and lingering distrust make the path to a durable agreement uncertain.Divergent Stances Within Iran’s Power StructureKey figures and institutions express markedly different thresholds for negotiation:Mojtaba Khamenei – son of the late Supreme Leader, author of written messages that stress a “resistance economy” and a future without U.S. presence.IRGC commanders – Ahmad Vahidi, Ali Abdollahi, Majid Mousavi and Mohammad Ali Jafari demand no major concessions, emphasizing deterrence, control of the Strait of Hormuz and a set of five pre‑conditions for talks.Saeed Jalili and the Paydari Front – hard‑line parliamentarians who view any compromise as a loss, insisting on guarantees that do not rely on “trusting” the United States.Government pragmatists – parliamentary speaker Mohammad Bagher Ghalibaf, President Masoud Pezeshkian and Foreign Minister Abbas Araghchi signal openness to a pragmatic deal that ends hostilities.Financial Stakes and Strategic DemandsNegotiations are anchored by concrete economic and security requests:Control and classification of vessel traffic through the Strait of Hormuz, including the right to levy transit fees.Access to at least 12 bn USD in frozen Iranian assets abroad.Removal of U.S. and United Nations sanctions linked to Iran’s nuclear programme.Release of frozen assets, war reparations and recognition of Iranian sovereignty over Hormuz as outlined by Mohammad Ali Jafari.Regional and Diplomatic ImplicationsThe internal split influences broader dynamics:Continued military exchanges between the U.S. and the IRGC raise the risk of accidental escalation.State‑run media and IRGC‑linked outlets amplify maximalist rhetoric, shaping public opinion against compromise.Hard‑line pressure could force the United States to offer stricter guarantees, potentially prolonging the stalemate.Any concession on Hormuz could alter global oil shipping routes and affect energy markets worldwide.Outlook: Scenarios for a US‑Iran AgreementAnalysts see three plausible trajectories:Stalemate – hard‑liners block a deal, extending the conflict and deepening sanctions.Limited Interim Accord – pragmatic leaders secure a cease‑fire and limited economic relief while broader issues remain unresolved.Comprehensive Settlement – a breakthrough that meets most of Tehran’s demands (asset release, Hormuz control, sanction lift) and includes security guarantees for the United States, leading to a gradual de‑escalation.The direction Iran ultimately takes will hinge on the balance of power between its hard‑line factions and the more moderate elements seeking an end to the war.

The Lead Pointing to a photograph of dry brown long grass hugging the shoreline, Gerardo Bolaños stands in front of a green oasis of seedlings and trees potted in black plastic bags. "This is what Playa Guiones looked like when we started in 2011," says the executive director of Costas Verdes, a Costa Rican nonprofit. The Coastal Transformation As howler monkeys growl in the background, Bolaños points to the picture next to it – an image of the same patch of land but with scores of flourishing, lush green trees. Today, he says, this is how the beach looks. The reason for the stark difference, says Bolaños, a straight-talking man with a coloured tattoo of the turquoise-browed motmot bird on his left arm, is a sustained tree-planting programme that Costas Verdes started in 2011. The Roots of Reforestation Costas Verdes was founded by then Costa Rican university student Max Tattenbach in 2009. A keen surfer, he wanted to restore the shoreline at his favourite surf spot, Playa Hermosa. "Playa Hermosa is about 6km [3.5 miles] of beach, and it only had one [area of] shade along the entire beach," says Tattenbach. "I used to go surfing there and take my then girlfriend and now wife. She didn't surf and liked to read and chill on the beach, but Playa Hermosa had no shade, so she didn't like going, and it started to become an issue. I promised her I would reforest Playa Hermosa so we could enjoy the beach." The Environmental Impact The project has transformed deforested Pacific coastlines into thriving ecosystems through a community-driven environmental project that has planted more than 100,000 native trees across 34 beaches, reviving wildlife habitats and combating decades of deforestation from cattle farming. Walk along the seafront in Nosara, over 100km further down the coast from Hermosa, and the plan appears to have paid off, with thousands of trees such as tropical almond trees, madero negro (Gliricidia sepium) and frangipani lining the trails and offering shade to beachgoers, creating a thriving ecosystem for wildlife. The Historical Context of Deforestation Bolaños, who joined the organisation as a volunteer in 2011, became project director three years later and executive director in 2024, says deforestation has changed the area's landscape. "Last century, we had great coastal forests all along the Pacific coast of Costa Rica," he says. Bolaños estimates that between the 1940s and 1970s, Costa Rica lost 70% of its forest cover, including along the Pacific coast. He puts this down to a boom in livestock farming. "Farmers burned the ecosystems and grew grass to feed the cattle. It was extremely aggressive, poorly planned," he says. "The beachfronts were devastated by cattle farming." The Future of Coastal Restoration What began as a personal quest for shade has evolved into a community-driven environmental movement with significant implications for coastal conservation. The success of Costas Verdes demonstrates how small-scale, community-led initiatives can have a substantial impact on environmental restoration, offering a model for other regions facing similar deforestation challenges. As climate change continues to threaten coastal ecosystems worldwide, the reforestation efforts in Costa Rica provide a hopeful example of how human intervention can help restore natural habitats and build resilience against environmental degradation.

The Lead: Court Intervention Amid Public OutcryKenya's High Court has intervened in the controversy surrounding a proposed United States-linked Ebola quarantine facility, ordering the government to disclose all details about the project. This decision comes a day after hundreds of people protested in the central town of Nanyuki, with reports indicating that two individuals died from gunshot wounds during the unrest.The court's ruling represents a significant development in a situation that has escalated from public protest to legal challenge, reflecting growing concerns about transparency and public health safety in the planned facility.The Court Order: Demanding TransparencyThe High Court extended conservatory orders that effectively stop the establishment of any Ebola quarantine, isolation or treatment facility in Kenya. The court also barred the admission of individuals exposed to the virus to the country.Crucially, the judges ordered the cabinet secretary for health to make public the agreement details, health and biosafety assessments, regulatory approvals, and operational protocols related to the facility. This comprehensive disclosure requirement aims to address concerns about the transparency of the US-Kenya agreement.This legal action follows an earlier court order from Friday that had temporarily suspended the plan after a lawsuit was brought arguing that the site could endanger public health.The Public Response: Violent ProtestsThe controversy has sparked significant public backlash, with hundreds of Kenyans taking to the streets in Nanyuki to protest against the planned facility. The protests turned violent, resulting in two fatalities from gunshot wounds, according to protest organizer Patrick Wahome and a security source cited by Reuters.The main petitioner in the court case, the Katiba Institute, has consistently argued that the plan poses grave risks to public health. During the hearing, the institute emphasized that the deal between the US and Kenya lacks transparency. They were joined in their opposition by the Law Society of Kenya and the main doctors' union, all calling for rejection of the facility.Government Position: Defending the FacilityDespite the court orders and public protests, Kenya's government has pledged to proceed with plans to establish the facility. Health Minister Aden Duale defended the project as part of a broader effort to strengthen emergency response systems in the country.President William Ruto also came out in defense of the facility, speaking about it for the first time. He characterized it as part of a wider national preparedness plan and a long-standing health partnership with Washington. Ruto explained that he approved the facility after US President Donald Trump requested Kenya's support, citing decades of cooperation on health programs including HIV/AIDS, Ebola, and COVID-19.The president emphasized that similar facilities already exist across Kenya and that the Laikipia Air Base facility would serve both Kenyans and foreign partners, including Americans, if needed. Ruto also highlighted that Kenya has prepared isolation, surveillance, and treatment facilities in 23 counties as part of its preparedness.Regional Context: Ebola Outbreak in Neighboring CountriesThe debate over the quarantine facility occurs against the backdrop of a significant Ebola outbreak in neighboring countries. The Democratic Republic of the Congo and Uganda are battling the rare Bundibugyo strain of the Ebola virus, which has so far killed 48 people.The World Health Organization (WHO) has declared this outbreak a public health emergency of international concern. The outbreak is reportedly outpacing the global response, which got off to a late start, adding urgency to regional preparedness measures.This regional context helps explain why Kenya and the US are moving forward with plans for the quarantine facility, despite domestic opposition.Future Implications: Path Forward for the FacilityWith the court demanding full disclosure of the agreement details, the immediate future of the Ebola quarantine facility remains uncertain. The government will need to provide comprehensive information about the facility's operations, safety measures, and risk mitigation strategies.The opposition groups, including the Katiba Institute, medical professionals, and legal organizations, will likely scrutinize this information closely for any potential gaps or risks to public health.Meanwhile, the regional Ebola outbreak continues to pose a threat, creating a complex situation where public health concerns must be balanced with transparency and public trust. The outcome of this legal and political battle may set precedents for how similar facilities are established and regulated in the future.

On 2 June 2026, municipal authorities in India ordered the dismantling of a towering statue of football legend Lionel Messi after safety experts warned that the structure could collapse under wind or seismic stress. The move, driven by public‑safety concerns, has ignited a broader debate about the cost, cultural impact, and regulatory oversight of large‑scale sports monuments. Statue Removal Sparks Safety Debate in Indian City Location: Gurugram, Haryana – a fast‑growing urban hub known for high‑profile public art. Height: Approximately 30 metres (98 ft), making it one of the tallest football statues worldwide. Timeline: Unveiled in March 2025; ordered removed on 2 June 2026. Reason: Structural analysis revealed inadequate foundation for local wind speeds and seismic activity. Cost and Scale: What the Numbers Reveal Construction cost: Estimated at ₹150 crore ($18 million). Materials: Bronze cladding over a steel framework, with a reinforced concrete base. Projected visitor revenue: ₹12 crore annually from ticket sales and merchandise. Demolition expense: Anticipated at ₹30 crore, roughly 20% of the original outlay. Ripple Effects on Sports Tourism and Public Art Policy Tourism impact: Local hotels reported a 15% dip in bookings since the removal announcement. Public sentiment: Fans expressed disappointment on social media, while safety advocates praised the precaution. Regulatory shift: The state government announced a review of all monuments exceeding 20 metres, mandating third‑party engineering audits. Economic considerations: Investors are re‑evaluating the ROI of large‑scale statues versus alternative fan‑engagement initiatives. What Comes Next for Mega‑Statues in India? Design revisions: Future projects are likely to incorporate modular, lighter materials such as carbon‑fiber composites. Community involvement: Municipalities may require public consultations before approving monumental art. Policy framework: Anticipated introduction of a "Monument Safety Act" to standardize engineering standards across states. Strategic pivot: Sports franchises could shift focus toward interactive digital experiences rather than permanent physical structures.

A Claustrophobic Vision of Near-Future EnglandRosa Rankin-Gee’s highly anticipated follow-up to Dreamland (2021), titled My Only Boy, delivers a darkly funny and politically charged dystopia. The novel paints a terrifyingly familiar picture of an England that has just elected a far-right populist government. For the reader, the gap between current reality and the novel's fiction feels increasingly suffocating, making the narrative function as both a gripping story and a stark warning.The Exploitative Mechanics of 'Gigr'At the heart of the narrative is Elle, the communications director for a gig-economy behemoth aptly named Gigr. The company connects desperate workers with immediate shift labor. The novel opens with Elle managing the reputational fallout of a worker's suicide—a tragic but common occurrence, as public sector wages no longer cover basic survival. Gigr's algorithms ruthlessly calculate the absolute minimum a desperate person will accept to pay for emergency healthcare or food, highlighting a brutal new era of automated exploitation.Moral Decay and the Human Cost of Algorithmic LaborThe narrative engine is driven by a tangled web of romance and corporate corruption. Elle, historically secure in her lesbian identity, begins a confusing romance with Ed, a newly famous gay author, while simultaneously engaging in a questionable affair with her much younger subordinate, Luisa. This power dynamic forces the reader to grapple with Elle’s increasingly loathsome, yet understandable, moral compromises. As environmental degradation worsens and white-collar crime deepens, the characters survive on a brittle diet of dark humor, alcohol, and repression.Setting: A near-future England plagued by extreme weather, violent crime, and massive wealth inequality.Core Conflict: Elle's internal justifications for violating labor laws versus her crumbling personal relationships.Thematic Tone: Cynical, flippant, and darkly comedic, contrasting sharply with the grim reality of the plot.The Enduring Relevance of Political DystopiaWhile the novel's final third occasionally struggles to balance its cynical humor with the intricate realities of corporate crime, Rankin-Gee’s sharp prose remains a standout. My Only Boy serves as a brilliant, albeit unsettling, mirror to our current socio-economic anxieties. It predicts a future where human rights are continually eroded by corporate efficiency, cementing its place as a vital read for understanding the psychological toll of modern political despair.

Grassroots Engineering: Paving the Way for Nigerian MotorsportIn a remarkable display of passion and initiative, a community of drifters in Nigeria has taken the ambitious step of constructing their own racing track. Faced with a lack of formal venues, these motorsport enthusiasts have transformed raw land into a functional circuit. This grassroots effort is not just about creating a space for local drifting; it represents a deep-seated ambition to elevate the profile of Nigerian motorsport on a global scale.The Infrastructure Gap in African RacingThe necessity for the drifters to build their own track underscores a significant reality in African motorsport: a severe lack of infrastructure. While regions like Europe and Asia boast numerous world-class facilities, aspiring racers in West Africa often have to rely on improvised spaces or abandoned roads. By constructing this track, the community is attempting to bridge this infrastructural divide, providing a safe and dedicated environment for the sport to grow.Primary Challenge: Severe lack of formal, paved racing circuits in the region.Community Action: Local drifters self-funding and building a track from the ground up.Ultimate Goal: Establishing a foundation that could eventually nurture Formula One talent.From Local Dirt to Global AspirationsThe driving force behind this labor of love is a dream that seems lightyears away for many: competing in Formula One. The journey from a locally built drift track to the pinnacle of global motorsport is historically unprecedented, yet it serves as a powerful motivational tool for the youth involved. It highlights a shift in mindset, where local racers are no longer content with just participating locally but are visualizing themselves in the highest echelons of international racing.The Economic and Cultural RoadblocksDespite the enthusiasm, the path forward is fraught with challenges. Motorsport is inherently capital-intensive. The costs associated with vehicle maintenance, safety equipment, and track certification are substantial. Furthermore, without major corporate sponsorships or government backing, sustaining the track and upgrading it to international standards will require significant financial innovation and community support.The Future of African Representation in Global MotorsportWhile an immediate leap to Formula One remains a long-term aspiration, the immediate impact of this project is the formalization of a local racing culture. If this track can host regional events and attract sponsorships, it could serve as a blueprint for other African nations. The initiative proves that the appetite for motorsport in Nigeria is strong enough to build foundations from the ground up, potentially paving the way for the continent's next generation of racing talent.

The Guardian reports that the 1939 painting Man in a Black Scarf, long dismissed by Lucian Freud himself, has finally been authenticated by experts and will be displayed publicly for the first time at the Garden Museum in London.The Long‑Running Dispute Over “Man in a Black Scarf”Created while Freud was a student at the East Anglian School of Painting and Drawing in Hadleigh, Suffolk, the portrait is believed to depict John Jameson, a friend of the artist and member of a prominent whiskey family. The work resurfaced on the BBC’s Fake or Fortune? in 2016, where historian Philip Mould deemed it “very likely a Freud”. Yet Freud repeatedly denied authorship, even after Christie’s initially identified it in 1985, prompting a 19‑year effort by the current owner, designer‑author Jon Lys Turner, to secure a formal authentication.Financial Stakes: From £300,000 Speculation to Multi‑Million‑Dollar BenchmarksIn 2016 the painting was speculated to be worth more than £300,000.Freud’s 2015 work Benefits Supervisor Resting sold for $56 million (£42 million).His auction record stands at $86 million.The upcoming Sotheby’s auction of Sleeping by the Lion Carpet carries an estimate of £25 million to £35 million.These figures illustrate how a single authentication can shift a work from modest speculation to a position within the multi‑million‑dollar tier of the contemporary art market.Why the Authentication Shifts the Post‑War British Art NarrativeThe confirmation links Freud’s early style directly to the teachings of Cedric Morris and Arthur Lett‑Haines at the East Anglian School, highlighting a previously under‑explored influence. Turner argues the portrait’s “confrontational gaze” and “thick, daubed paint” reveal Freud’s early adoption of Morris’s techniques, potentially prompting a reassessment of other student‑era works.What Comes Next for the Painting and the Market"Man in a Black Scarf" will open to the public in the 2 June – 20 September 2026 run of the exhibition Benton End: A Paradise of Pollen and Paint. The exposure may spur renewed provenance research on other disputed Freud pieces and could encourage collectors to revisit works from the East Anglian period, driving further market activity ahead of the Sleeping by the Lion Carpet auction.

A Critical Portrait of George MichaelIn 1998, George Michael was arrested for public lewdness in an LA lavatory, an incident that finally led the singer to publicly come out. The following day, Sathnam Sanghera found himself unable to leave his room at university: the doorway had been mockingly plastered with tabloid newspaper headlines – "ZIP ME UP BEFORE YOU GO-GO!" – by fellow students aware of his longstanding fandom. As a writer, Sanghera is best known for a series of award-winning books on the British empire, which he calls his "specialist subject". Judging by Tonight the Music Seems So Loud – not a biography so much as a miscellany, a set of themed essays that tend to digress in all kinds of intriguing directions – the life and work of one Georgios Panayiotou runs imperialism and its legacy a very close second.The Complex Legacy of a Pop IconIt is an unashamedly partisan book, although not an uncritical one. Sanghera is as alive to Michael's personal and professional failings (whether the naffness of some of his early work as one half of Wham! or his high-handed treatment of the duo's other half, Andrew Ridgeley) as he is in love with his artistic triumphs. These, of course, range from Careless Whisper and Wham!'s annually inescapable Last Christmas to the 1996 solo masterpiece Older, a peculiar and peculiarly effective cocktail of raw grief at the Aids-related death of his lover Anselmo Feleppa and unrepentant horniness.The Evolution of Critical ReceptionSanghera's love for his subject is evidently sharpened by the opprobrium of others. Indeed if the book has a flaw, it's that the author is old enough to remember an era when George Michael was deemed insufferably uncool by some arbiters of taste (incredibly, when Wham! performed at a 1984 benefit show for striking miners, the only mainstream pop act to show support for the cause, they were received stone-faced by the audience and savaged by the music press for their trouble), and thus has a tendency to underestimate how much both he and his music have been critically re-evaluated in the 21st century.The Artistic Journey of George MichaelHe says one of the spurs to write the book was his belief that "most truly popular music is not generally deemed worthy of serious analysis and George Michael's music most certainly is not". That might have been true once, but certainly not of late: when he died, this newspaper alone ran six features by critics analysing different aspects of his music. "He sang so exquisitely about the marrow of life, about the vital, corporeal things", wrote one, which definitely doesn't amount to taking George Michael insufficiently seriously.double quotation markEven as he skinned up in front of journalists and discussed his drug use and sex life, he was concealing the extent of the addictions that eventually killed himFamily Background and Cultural IdentitySanghera is very good on the climate of homophobia in the 80s, which might have given any gay public figure serious qualms about coming out, and fascinating on Michael's family background: how growing up embedded in north London's Greek Cypriot community impacted on everything from Wham!'s image – not camp, Sanghera suggests, but "the vision of two children of immigrants imagining a kind of glamour they had not actually experienced before" – to his work ethic and control freakery. His dad made good in England by working exceptionally hard, running such a tight ship at his restaurant that he summarily fired his only son for messing up the drinks orders. The fact that the same son went on to hire 12 different saxophonists before finding one that could play the solo on Careless Whisper to his satisfaction doesn't come as a huge surprise.The Perfectionist and Contradictory ArtistThis my-way-or-the-highway perfectionism could yield hugely impressive results – Careless Whisper's sax hook may well be the most famous in pop history – but it could equally lead to intransigence and self-sabotage. Michael worked incredibly hard to transform himself from a member of a teen pop band into a more adult-facing solo artist, but having sold a staggering 25m copies of his 1987 solo debut Faith, he refused to promote its follow-up Listen Without Prejudice Vol. 1, or even make videos for its singles: a better album than its predecessor, it achieved only a fraction of its sales as a result. It was evidence of a deeply contradictory nature that occasionally has Sanghera throwing up his hands in bewilderment.The Public and Private Faces of George MichaelMichael was a polymath, keen to be duly credited as the sole singer, writer, producer and musician on a succession of tracks, but also had a weird habit of talking down his abilities, claiming he couldn't play instruments he was perfectly capable of playing. He was a Stakhanovite who increasingly worked at an agonisingly glacial pace, endlessly fussing over details, a state of affairs not much helped by his gargantuan appetite for marijuana: coupled with bouts of writers' block, it meant he released only six albums of original material in a career that lasted 34 years. He was a Labour voter, booster of the NHS and famously generous philanthropist who also engaged in tax avoidance. After being publicly outed, he became a notoriously frank interviewee ("as if nothing can embarrass him anymore" the Guardian's Simon Hattenstone suggested when he met him in 2009). But even as he skinned up in front of journalists and freely discussed his drug use and sex life, he was concealing the extent of the addictions that eventually killed him.The Decline and Final YearsMichael emerges as a messy, unpredictable but ultimately hugely likable figure, which makes the essay about his demise particularly tough reading. Listed starkly on the page, the facts of his final 10 years make it obvious that he was a deeply unwell man whose life had spun wildly out of control: drug busts, medical emergencies, visits to rehab, rumours of breakdowns and suicide bids and seven incidents in which he either crashed his car or was found comatose at the wheel.The Professional Mask of Personal StruggleThat it somehow didn't appear obvious at the time – that his death at 53 felt like a shock rather than a grim inevitability – seems remarkable, but as Sanghera points out, Michael's professionalism did a lot to paper over the cracks. He was always available to the media and always smart, funny and self-effacing: to use a modern turn of phrase, he controlled the narrative. He was punctilious about his appearance – the star certainly never looked like an ailing drug addict – and unfailingly superb onstage.The Hidden Realities Behind the FameBehind the scenes, it was a different story. He struggled to make new music: at one juncture he booked six months of recording sessions but never turned up to the studio once. His once-acute commercial instincts seemed to desert him: even Sanghera can't muster much enthusiasm for the handful of still-unreleased songs he completed in his final years. He cut off close friends and family who tried to intervene. No one who knew him seems to have been particularly surprised by his death: the list of adjectives used to describe him on his official website now includes not just "icon" "legend" "soul singer" and "philanthropist" but "addict" "repeat offender" and "depressive".An Imagined Alternative LegacyAs the book draws to a close, Sanghera offers a heartbreaking alternative history. He imagines Michael conquering his addictions, coming to a complete accommodation with his musical past (to the end of his life, he was dismissive of Wham!, describing their oeuvre as an exercise in "ignoring my own intelligence" and declining to play most of their hits live) and headlining Glastonbury, "getting pleasure from the audience reaction to Club Tropicana".The Enduring Power of George Michael's MusicIt's affecting because you can imagine it so vividly: the endless succession of hits that anyone with even a passing interest in pop music knows, the pandemonium in the crowd when he breaks out Careless Whisper, the encore of Freedom '90. You don't have to be a fan on Sanghera's level to understand what a triumph it would have been.

The Ancient Art of Altamira The aurochs, the mammoth, and the steppe bison are long extinct, but their painted likenesses still look relatively fresh across the walls and roofs of Altamira. Or so said Diego Garate Maidagan, who is one of the very few humans allowed to enter that exalted cave in northern Spain. The Technique of Prehistoric Painters Garate's specialism requires close attention to the etching or “pecking” technique whereby the artists used flint blades to outline figures on the rock before applying their ochre and charcoal. Altamira is rare and precious, he told me, because those reds and blacks are still so solid and vivid. The colours were preserved in the near-quarantine conditions imposed by that long-ago landslide. The Impact of Human Presence on Cave Art The site was opened to the public in 1917, partly closed in the 1970s, then shut for good in 2002, as a century or so of gaping admiration revealed the paint-stripping effects of moisture and carbon monoxide from the breath of too many beholders. A replica cave, with replica artwork, was created on an adjacent site. Today, only Garate and other select scholars have access to the original sanctuary. The Future of Cave Art Research In the far north of the Basque Country, the recent search for such apparitions has stirred “a little revolution”, by Garate’s reckoning. He and his colleagues in Santander planned a campaign to test a working theory: that the caves of northern Spain and south-western France were once lavishly decorated with pictograms and petroglyphs, now barely visible to the untrained eye. Unlocking the Secrets of Prehistoric Image-Making The general idea, Garate told me, was to reverse-engineer the processes of prehistoric image-making: to unpack the practical, mechanical decisions of the artists, and thus to better understand their skill set, their knowledge base, their means and modes of communication. One project gauged the “luminous intensity” and “radius of action” achieved by burning different woods and fats to light the cave.
