Aivela, also known as the Favored Daughter, served as the zealous goddess of ardor. She was one of the six main Old Gods, the divinities venerated by the inhabitants of the world of Zakuul before Valkorion rose to become the undying Emperor. Being one of the four offspring of Izax and Scyva, Aivela was the sibling of Esne, the goddess embodying envy. Aivela stood beside her brother Tyth in combat, illuminating brave soldiers with her radiance.
Aivela's beginnings trace back to an experimental titanic wardroid superweapon from Iokath, crafted by a technologically superior, ancient civilization. Alongside her five siblings, she underwent trials on several unsuspecting planets, resulting in more than ten trillion deaths. Zakuul was one of these worlds, which explains why Aivela was a figure of worship on that planet.
