Idoneth Deepkin

To most in the Mortal Realms, the Idoneth Deepkin are nothing but a myth – a story of daemons from the sea, told to frighten little children into obedience. The truth is far more terrifying, for when the Idoneth Deepkin emerge from the ocean depths, they come to claim the souls of the living. Theirs is a tragic tale. In the Age of Myth, not long after the dawning of the realms themselves, the Mage God Teclis and his brother Tyrion awoke in the realm of Hysh, newborn divinities of aelfkind. Together with the other aelven gods, they hatched a plan to avenge themselves on Slaanesh – the gluttonous Chaos God who hungered most strongly for aelven souls.

They captured and imprisoned the Dark Prince, and using an arcane tool known as the Ocarian Lantern, Teclis drew countless lost aelven souls from its belly, one by one. These spirits were distributed amongst the aelven gods, and Teclis used his portion to craft the ideal aelves of his imagination, naming them Cythai, or the Awakened. Yet, somehow, they were flawed – none of the Mage God’s attempts to purify their tarnished souls bore fruit, and eventually the Cythai fled their father in fear, hiding from his scrying gaze in the oceanic depths.
