Keph
Keph was a Primal God member of the Third Circle. She lived within the Undervault and had hundreds of chitinous appendages that acted as her arms and legs. Her eyes, two large orbs, were filled with many facets, giving her the name She of Many Eyes.
Keph was known to have legendary insights for, though she wasn't Soulless, Dynara had permitted Keph's mind to be touched briefly by Magnora. So great was her ken that the Fates discussed with her things they trusted no other god to understand. Keph dictated a collection of predictions to Mugowumpois known as the Verses of Magnora that continue unfold to this day.
Following the first battle of the Elder Wars, Illith the Leviathan broke through the defenses of the Elder Gods and confronted Keph directly in the Undersea. They battled for over a hundred days consecutively before Illith returned to the surface, split in two. Keph had died in the process of forever weakening the Leviathan.
Keph lives on, having splintered into the mortal race of kephera.
