Black Book

Black Book is set in the rural Slavic countryside of the 19th century, and its world is constructed from real Northern Slavic folklore researched with expert anthropologists. Vasilisa, a young woman destined to become a witch, abandons her fate to marry her beloved — until he dies under mysterious circumstances, and she takes up the Black Book instead, a seven-sealed demonic artifact that grants any wish to whoever unlocks all of it.

Combat is card-based, with spell cards unlocked through progression and decks that grow as you absorb new abilities. Demons in your service serve as your familiar flock — useful when you can keep them occupied, dangerous when they're idle, because idle demons torture you for entertainment. The structure rewards keeping the supply of tasks high.

The campaign unfolds as an adventure across the countryside, performing exorcisms, solving the woes of common folk, and gradually closing in on the seals. An in-game encyclopedia documents the folktales and mythology the game draws from, and side quests illuminate specific local traditions. Morteshka's Russian studio built the project as a serious folkloric adaptation rather than a generic fantasy reskin.
