Ukkoto Umberhand, Eater of the Light is one of the Elder Dark..
Story
Ukkoto displayed an unmatched capacity for quenching light. The only obviously active Elder Dark since the return of light, he intended to extinguish the Ashen's light. To this end he hunted Gefn who created a echo of Amara to serve as her protector.
He stole Sissna's cauldron, tore off one Riak's talons, and broke Amara's lyre.
