Aivela

Aivela, loved as the Favored Daughter, was the fiery goddess of passion among the six primary Old Gods, the deities worshiped by the people of the planet Zakuul prior to Valkorion's ascension to Immortal Emperor. One of the four children of Izax and Scyva, Aivela was the twin sister of Esne, the goddess of jealousy, and Aivela accompanied her brother Tyth on the battlefield, where she shone her light on fearless warriors.

Aivela originated as an experimental Iokath titanic wardroid superweapon, built by an ancient, but highly advanced people. She, along with her five brothers and sisters, were tested on several unsuspecting worlds, leading to over ten trillion casualties, one of the worlds being Zakuul, which is why Aivela was worshiped there.
