About this game
You signed the indenture. The page was still warm.
Grimsorrow Academy is an idle RPG of dark academia and spellcasting dread - two games in one save, narrated by a clerk who has read your file and found you wanting. Scry a black mirror for the dark itself. Attend fifteen forbidden Disciplines. Every ten years, sign again for more power. The school never lets you graduate. It only lets you go deeper.
Scry the Obsidian Mirror to unlock your Disciplines and advance through the school year. Spells can be cast to move faster, but the ledger balances, and everything is paid for.
Spells are not bought. They are learned and trained by hand. Trace a spell's mark on the glass to cast it: instant Maledictions, sustained Litanies, and Bindings that scry in your place. Only the strongest learn to cheat their own examinations and idle them.
Discover the fields of study: gravebotany, cryptmining, blackforging, hexweaving, and more. Master each action for permanent perks; craft the gear and potions that see you through the Night Errands. Bank enough Attunement and the darkest crafts of the Academy open to you.
After curfew, the Professors keep a list, and the lists have teeth. Fight across 23 zones, 12 dungeons and over 90 monsters. Harness their unique drops and sets, then take them to the Anvil that reforges gear +N until it sings (or shatters).
When the umbra runs deep enough, sign a new Indenture. It shatters the mirror and voids your contract - and pays you for both: Seals that bless every life after this one, and Oaths spent down a permanent tree. You keep the power. You keep signing.
Earn Tenure and raise your ceiling across 120 levels. A second realm opens beneath the Winding Stair: the Undercroft; and below that the Maw; and below that, what the lore will not decipher. All stairs here go down.
