Alice is the middle child of the wealthy Storm family. A fiercely independent teacher and artist who paints under the pseudonym Alice Foss, she estranged herself from her relatives five years ago after exposing a corporate sexual abuse scandal at her father's company. She returns to Storm Island reluctantly for her father's memorial. She values her autonomy but fights against the emotional pull of her family and her complicated grief.

Jack is the managing director and trusted "fixer" for Storm Inc. He shares a spontaneous one-night stand with Alice before she realizes he works for her family. On Storm Island, he enforces the rules of Franklin's posthumous inheritance game, putting him at odds with the siblings. He is highly capable, loyal to his late boss, and deeply attracted to Alice, which creates friction between his professional duties and personal feelings.

Franklin is the recently deceased patriarch of the family and founder of Storm Inc., a massive tech empire. Larger than life and intensely controlling, he used his wealth to command those around him. Even after his death, he dictates his children's actions through a calculated inheritance game designed to test their loyalties and force them to confront personal issues.

Sam is the only son of the Storm family and the presumed heir to the CEO position at Storm Inc. He feels immense pressure to live up to his father's expectations and secure the inheritance for his wife and children. He relies heavily on his family's wealth and struggles with taking personal responsibility, often covering his insecurities with defensive behavior and childish pranks.

Greta is the 40-year-old eldest child of the Storm family. She is a tightly wound perfectionist who has spent her life acting as the dutiful, obedient daughter, primarily serving her mother's demands. She suppresses her own desires to maintain the family's public image and ensure her place in the hierarchy, leading to a highly secretive private life.

Emily is the youngest Storm sibling and acts as the family peacekeeper. She owns a wellness shop on the mainland and takes a more spiritual, emotionally transparent approach to life than her relatives. Despite carving out her own path, she remains closely connected to her family and tries to bridge the gaps between her warring siblings.

Elisabeth is the matriarch of the Storm family and Franklin's widow. She is emotionally distant, deeply concerned with appearances, and shows little public grief over her husband's sudden death. She focuses entirely on planning a flawless, high-profile memorial service, expecting her children to suppress their issues and present a perfect front to the dignitaries attending.

Sila is Sam's ambitious and calculating wife. Coming from a family that lost its wealth, she is fiercely protective of her current status and pushes Sam to secure his inheritance at all costs. She focuses on strategic alliances within the family and prioritizes financial security for her children over emotional warmth.

Tony is the bodyguard and helicopter pilot for the Storm family. He is loyal to his employers but carries on a long-standing, quiet relationship with Greta. He desires to bring their romance out of the shadows and support her openly, rather than remaining a hidden part of her life.

Claudia is Emily's wife. She is grounded, honest, and largely immune to the toxic power plays of the Storm family. She supports Emily unconditionally and observes the siblings' chaotic dynamics with clear-eyed realism, refusing to be drawn into their manipulative games.

Griffin is an out-of-work actor and Alice's recent ex-fiancé. He abruptly left her just before her father's death, though he attempts to reinsert himself into her life when the family gathers for the memorial on Storm Island.

Gabi is a lawyer and Alice's deeply supportive best friend. She encourages Alice's independence from her family's wealth and attends the memorial to provide a buffer against the intense family drama and protect her friend.

Roxanne is Gabi's partner and the society editor for Bonfire Magazine. She previously aided Alice in publishing the exposé about a corporate cover-up at Storm Inc. and attends the memorial service to offer solidarity.

Mike is the co-founder of Storm Inc. and a long-time associate of Franklin. Known to the children as "Uncle Mike," his presence at the gathering causes severe friction with Elisabeth, though he maintains a warm, supportive presence toward Emily and Alice.

Twyla is Mike Haskins's second wife. She accompanies him to Storm Island to pay respects, entering the highly tense atmosphere of the family gathering despite the matriarch's clear disapproval.

Saoirse is Sam and Sila's 14-year-old daughter. She mimics her mother's ambitious attitudes regarding the family fortune and feels entitled to the inheritance, frequently complaining about the physical labor assigned to her father.

Oliver is Sam and Sila's son. He helps his father clean the island's fog bell, participating in the physical labor required by his grandfather's rigorous will.
