Game Overview
Immortality turns poisonous beneath the waves in a choice-driven fantasy RPG set within the dazzling but politically fragile City of Glass. You play a merfolk protagonist living under an ancient bargain: whales grant your people eternal life, while merfolk preserve secrecy and stand against the monstrous squid. When a rebel threatens to break that arrangement, personal desire, civic duty, and old resentments collide. The mood is romantic, introspective, and occasionally ruthless, with every major decision carrying emotional weight rather than simply sorting choices into good or evil.
Play unfolds as a substantial interactive novel, with your selections shaping your identity, alliances, romances, and ultimate fate. Rather than traditional combat systems or loot grinding, the challenge comes from reading people, judging competing claims, and accepting the cost of your convictions. You define your mer-self through flexible gender and orientation options, then navigate relationships with fellow citizens and visiting humans alike. Trust works as a central resource: characters remember your actions, respond to betrayal, and can become devoted partners, wary allies, or casualties of your ambition. Branching routes lead toward more than ten endings, encouraging repeat runs built around different loyalties and moral priorities.
The Sea Eternal stands out through its underwater society’s layered conflicts, where immortality is not a reward but a source of stagnation, inequality, and control. Its prose-first format leaves the visual details entirely to the player’s imagination, making it a strong fit for readers who enjoy character-focused interactive fiction over action-heavy RPGs. Fans of Choice of Games-style narratives, visual novels without artwork, or political fantasy will find plenty to unpack in its 283,000-word script. Newcomers can enjoy a single dramatic story, while veterans of branching fiction have good reason to revisit the City of Glass and test how far different choices reshape its future.
