About
Sigils of Nightfall is a roguelike deckbuilder that combines dungeon crawling with elements of the award-winning RPG, Mörk Borg. Embark on a dark journey, improve your character, and survive at all costs — or be consumed by the horrors lurking in the darkness.
Story
You are a wandering lost soul, caught in the depths of the dreaded Mountain's Penance, a dungeon-like prison of despair and horror, where a mysterious cult is conducting heinous rituals to summon a demonic entity that will bring about the world's end, known as Nightfall.
