EITR is an action role-playing roguelike with fantasy elements and an isometric view. The Shield Maiden, like all mortal Norse, had to receive her destiny from the three fate-weaving norns and their sacred loom before she even entered the world. However, her destiny was ruined when the mischievous god Loki intervened, dripping stains of the wretched substance Eitr onto the loom, forever changing the path of the Shield Maiden and plunging the great tree Yggdrasil into darkness. Now the main character must travel to nine Scandinavian worlds connected by Yggdrasil and unravel the mystery of her destiny.
