Benji is a young Irish deckhand who worked aboard the *Galaxy* before its disastrous sinking. In the chaos of the lifeboat, he quietly records the harrowing experience in a diary addressed to a woman named Annabelle. He harbors deep, private guilt over the circumstances of the wreck and observes his fellow castaways with cautious skepticism, particularly the mysterious stranger they pull from the sea.

LeFleur is a middle-aged police inspector stationed on the small Caribbean island of Montserrat. Struggling with depression and a strained marriage following the tragic death of his young daughter, he frequently turns to quiet vices to cope with his grief. Discovering Benji's diary in the washed-up lifeboat offers him a profound distraction that challenges his cynical worldview.

Introduced primarily as a mysterious young man pulled from the water after the yacht's sinking, he calmly introduces himself to the desperate survivors as "the Lord." (A silent little girl named Alice is also present on the raft). He barely interacts with the panicked crew, instead offering paradoxical statements and insisting he can only save them if they entirely believe his claim.

Lambert is a wildly successful billionaire hedge-fund owner and the proprietor of the *Galaxy*. He organized an exclusive summit to gather the world's most influential people, only to find himself trapped on an equitable, crowded life raft. Arrogant and narcissistic, he refuses to accept his lack of control and frequently lashes out at the other survivors.

Geri is a former Olympic swimmer from California who attended Lambert's summit as a fitness entrepreneur and humanitarian. Among the panicked castaways, she emerges as a natural leader, using her athletic prowess and practical intelligence to organize survival efforts, patch the damaged raft, and maintain group morale.

Annabelle is a deeply loved woman from Benji's past. Adrift and facing death, Benji uses his diary to speak directly to her, pouring out his regrets, memories, and confessions. She serves as his emotional anchor to the life he left behind on land.

Patrice is Inspector LeFleur's wife. In the wake of losing her young daughter, she has leaned heavily into her faith, creating a profound ideological divide between her and her cynical husband. She lives in a state of quiet mourning, sharing a home that feels empty and tense.

Dobby is Benji's cousin, a man who harbors intense resentment toward the wealthy elite who gather to decide the fate of the working class. Benji's memories of Dobby's desire for justice deeply color his understanding of why the *Galaxy* sank, bringing a sense of looming threat to his past.

Jean Philippe is a survivor of the *Galaxy* who spends his time on the raft desperately caring for his severely injured wife, Bernadette. Deeply devoted and emotionally shattered by her condition, he eagerly approaches the mysterious stranger for a miraculous healing.

Bernadette is Jean Philippe's wife, severely injured during the sinking of the superyacht. She serves as a focal point of concern for her husband and a test of the stranger's supposed divine powers.

Yannis is a highly successful Greek businessman and international playboy who helped guide his country out of a financial crisis. Pragmatic and grounded, he relies on science and logic, frequently challenging the stranger's claims and attempting to rationalize their terrifying situation.

Nina is one of the frightened castaways who looks to the mysterious young man for immediate salvation. Her anxiety represents the broader panic of the group as she pleads for an end to their suffering.

Often referred to as Mrs. Laghari, she is a resilient woman who rose from poverty in India to become a globally affluent figure. As an esteemed guest of Lambert's, she finds her immense wealth entirely useless against the raw elements of the ocean.

Nevin is an influential British television producer and a former Olympic-level athlete. As his physical condition deteriorates in the cramped lifeboat, he begins to deeply regret his past personal failings, particularly his shortcomings as a father to his three children.

Lilly is Jarty and Patrice LeFleur's daughter, who drowned in a tragic beach accident at the age of four. Though she is gone, her memory casts a long, painful shadow over her parents' lives, defining their current emotional estrangement.

The local Police Commissioner on Montserrat oversees LeFleur's investigation. Aware of the immense public interest in the *Galaxy* disaster, he is eager to manage the situation properly and handle the inevitable influx of media attention.

Katrina is LeFleur's secretary at the Montserrat police station. She assists in navigating the chaotic logistics and media inquiries that flood the department once news of the lifeboat breaks.

Valerie is a news reporter who was stationed aboard the superyacht to cover Lambert's exclusive summit. Her abruptly terminated broadcast provides the mainland with its last glimpse of the doomed vessel.
