Nayu

Nayu is the king of the One-Horned Tribe, universally called the Martial King, and one of the strongest beings in the Tower—the only one of the Nine Kings able to rival the Summer Queen in individual might. Father of Phante and Edora (and 70+ children) and elder brother of the Spear God, he bears his tribe's purple hair, golden eyes and single curved horn.

Nicknamed the 'Walking Disaster' and 'The First Star,' he took three disciples over his life: the Sword God, Nocturn, and finally Cha Yeon-woo. Struck by Gaia's curse and assassinated by Asgard, his original soul was fragmented and scattered across worldlines as 'Starlight'; he is later revived through a shadow-self retrieved from the 21st Floor.
