Fury's Heart

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.

Description
As a Fiendish plane, Fury's Heart was host to a segment of the River of Blood which flowed through Malar's realm, the Land of the Hunt. A branch of the river also connected to Umberlee's Blood Sea. Other than Astral plane travel, the only other known access was via a portal somewhere beneath the crashing waves of the Blood Sea, connecting it to the Fated Depths.

At first glance, this plane was similar to the Barrens of Doom and Despair, with vast stretches of desolation and weather extremes, but unlike the Barrens, this plane was teeming with life that fought tooth and claw for survival. Except for Malar's realm, the whole plane was buffeted by violent storms, thunder and lightning, blizzards of rain, sleet, and snow, and hurricanes. Wind speeds rarely dropped below 31 mph (50 kph) as the Gods of Fury lashed the land and the inhabitants without mercy. In the Land of the Hunt, Malar moderated the weather somewhat to enable tracking skills, scent, spore, vision, and hearing to be used, enhancing the thrill of pursuit.

The Land of the Hunt shared a border with the other three realms on this plane. From the shores of the Blood Sea, Malar's vast open plain extended countless miles inland. Where the landscape turned into rocky foothills, this was the start of Talos's realm, the Towers of Ruin, eventually becoming steep barren hills of stone. In the opposite direction, the temperature eventually began to drop and rolling plain gave way to frozen tundra as the border of Auril's realm, Winter's Hall, was crossed.
