Fury's Heart was a Fiendish plane in the World Tree cosmology model. It was the home plane of the Gods of Fury, Auril, Malar, Talos, and Umberlee until the Spellplague scrambled the cosmos. In the wake of that world-shaping event, it merged with the House of Nature to form the Deep Wilds, except for Talos's portion, which the aspect of Gruumsh took with him to Nishrek.
