Illith, the Leviathan, is one of the Soulless and was one of the most powerful Heralds of Magnora at the onset of the Elder Wars. Following the first battle with the Elders, Illith broke through the defenses surrounding Lusternia and confronted Keph in the Undersea. Though the Leviathan managed to kill Keph, she was cleaved in twain by the Many-Eyed, significantly weakening Her. She was responsible for fatally wounding Orlachmar.

- Part of her eventually splintered to become the illithoid race.
