Io

The creator deity and Lord of All Dragons, sometimes also called Asgorath or Kukul. Io can be referred to using any pronouns. They are parent of both Bahamut and Tiamat, who in turn spawned the rest of dragonkind. He is also responsible for the Rending of the Planes, separating Zameen and the other planes from the Primordial Chaos. Additionally, she is one of a few rare entities to be considered both a deity and a Primordial.
The Sea of Io on Zameen is named in honor of the god. Additionally, the Iwi of Kainga Whenua feel a great connection with the deity and consider themselves his people.
