Quasi-Elemental Plane of Ash

The Quasi-Elemental Plane of Ash was the Inner Plane at the intersection of the Elemental Plane of Fire and the Negative Energy Plane. It was a place that sucked the warmth from any living creature.

History
Records found inside of an abandoned citadel on the world of Oerth hint that a community of dwarves may have tried to establish a colony in this plane, though their fate was unknown.

Notable Locations

 * Citadel of Former Flame: the home of Gazra, a creature who claimed to be the archomental of this plane, and the capital of the ash quasi-elemental empire. A variety of undead guarded the citadel including ghouls, spectres, and wraiths. The citadel itself was made from the very ash of this plane, carved and magically fused together, and was constantly altering its form in a gradual manner. Inside it was devoid of both heat and light. Both mundane and magical forms of illumination wouldn't function within it.

Inhabitants
The two most predominant sentient species on this plane were ash mephits and ash quasi-elementals. The former lived in scattered communities, while the latter had a substantial empire centered around the Citadel of Former Flame.

There lived a roaming group of ghasts and ghouls on this plane, numbering in the hundreds, that were referred to as the Flesh Renders. Due to going great lengths of time without any sustenance, they were particularly savage undead. Some speculated that they may have once been minions of Vecna.
