Black Equation is a dark fantasy interactive book — a text-based narrative game where every word matters, and every silence has meaning. This story was written during a period of deep depression, not as a product, but as a way to stay connected to the world. When social networks felt empty and unreachable, writing became the only language left — a way to speak honestly, quietly, and without masks. Black Equation is that conversation, transformed into a world you can enter. There are no images here. No fast action. Only text, atmosphere, and choices that slowly shape what you are allowed to see — and what remains hidden. About the Story In the medieval kingdom of Highgard, the greatest threat is not monsters or ancient curses, but the king himself. A ruler who despises his own people dares to challenge fate, defy the gods, and sacrifice what is most precious to him. His goal is not salvation, but erasure — to destroy Highgard and seize the neighboring throne of Valtoria, ruled by his own nephew. As magic spreads like a slow poison and political intrigue tightens its grip, three lives are drawn into the coming collapse: Yinyue — an impulsive young mage whose compassion often outweighs caution, willing to burn herself to save others. William — a restless young man avoiding responsibility, torn between desire and duty, drifting until choice becomes unavoidable. Charles — a loyal knight divided between honor and truth, quietly searching for love in a world hostile to honesty. Love, loyalty, betrayal, and forbidden choices intertwine as one question becomes impossible to ignore: what if Highgard’s destruction cannot be stopped — only understood? Gameplay & Experience Black Equation is a fully text-based interactive fiction experience. Your choices do not change everything — but they change what is revealed, what remains hidden, and how the world speaks to you. A pure text-based dark fantasy adventure Choice-driven narrative with multiple endings Psychological, emotional, and atmospheric storytelling A slow, calm reading experience designed for immersion Hidden paths, unrevealed truths, and endings that cannot be seen in a single playthrough LGBTQ+ characters and diverse relationships woven naturally into the world A Personal Work I am not a large studio, and this is not a polished commercial product. Black Equation is a sincere, personal work — written to survive, to reflect, and to speak with the world through story rather than noise. If you enjoy interactive fiction, visual novels, psychological narratives, dark fantasy worlds, and stories shaped by lived experience rather than formulas, this may become a quiet place for you — for a few evenings, or longer.
