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 . The Blood Rift randomly became coterminous with this plane , allowing creatures and conflict to spill over into Fury ' s Heart . 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 more effective , 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 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 . Inhabitants . Petitioners that arrived on this plane often took the form of primitive animals that matched their cruel spirit and evil disposition , shark s , for example , in Umberlee ' s realm , and large , land - based carnivores in Malar ' s realm . For prey to hunt , souls were regularly stolen from the Fugue Plane and made to take on the form of weaker or timid animals . Other petitioners took on a more elemental form representing the violence and indifference of nature at its worst , such as icy spirits in Winter ' s Hall or sentient lightning flickering around the Towers of Ruin . Natives of Fury ' s Heart included abrian s , bloodthorn , ice paraelemental s and other cold - natured extremophiles , ironmaw , khaasta , myrmixicus demons , nightmare s , fiendish squid , phiuhl , all varieties of varrangoin , vorr , vultivor canomorph s , and yeth hound s . Near the top of the food chain were various dragons : howling dragon s , pyroclastic dragon s , and the styx dragon s that patrolled the River of Blood . The pervasive evil of this plane attracted night hags and vargouille s to make their home here . Due to the occasional connection with the Blood Rift , arrow demon s could be found on this plane .
