Ayrzul has existed since the earliest days of the Elemental Planes, during which he shared control of the Plane of Earth with his rival Sairazul, one of four good elemental lords. Initially, the good elemental lords had the upper hand, while their evil rivals were disorganised. However, as life evolved on the Universe and started using the elements for evil purposes, the situation reversed. While the good elemental lords started bickering, Ayrzul and fellow evil elemental lords Ymeri and Hshurha were gathered under one banner by Kelizandri, and together they defeated their good rivals one by one and sealed them away.4
Shortly after he defeated Sairazul, Ayrzul encountered the xiomorns, who were originally created by his rival but had forgotten about her. He craved the mythic essence that Sairazul imbued into the xiomorns, and showed them a vision of their race going extinct during a mental invasion of the yithians. He then asked them to sacrifice a quarter of their number so he could have the power to teach the rest how to forestall their demise. The xiomorns, appalled by this suggestion, nonetheless believed Ayrzul and decided to sacrifice the mythic essence of half their number instead, granting Ayrzul the same influx of primordial power. In exchange for their essence, Ayrzul gave the xiomorns knowledge of the Vault Seeds.5
Ayrzul rules the realm known as the Blistering Labyrinth on the Plane of Earth. For eons, he had never been seen outside his realm, giving rise to speculation that he was somehow bound to the region.3
In truth, he patiently laid in wait to secretly scheme against his foes, many of which were imprisoned in his quest for total dominion over the elements. His victories included raiding the Plane of Metal for its powers over radioactive metals, and repelling an invasion by the elemental lord Verilorn of the Plane of Wood. The latter success also caused the retreating forces to return to their home plane with a radioactive plague.1
Ayrzul shows little interest in the politics of the Plane of Earth; he is seemingly content with maintaining the status quo. Instead, he concentrates his efforts against the Plane of Fire and his hated rival Ymeri, the Queen of the Inferno.3
Ayrzul considers the xiomorns to be his favoured children, and they in turn see him as their patron, if not their god.7 Their veneration of him, however, has been in decline since their migration to the Universe.1
