Rend takes place on a fragment of land that once was Midgard before Ragnarok, the doom of the gods, shattered the world. Valhalla, the great hall of heroes, home of the dead who achieve glory in battle, can be seen decimated in the skies above. What remains of this world is a collection of disparate environments held together by the massive roots of Yggdrasil, the World Tree. Gentle hills give way to dense forests, fungal colonies, noxious swamps, and wintry peaks, each home to predatory beasts and environmental challenges.
