The original chaos, a beast from primordial darkness who destroyed the isles of Namira's brethren and blocked the magic of Earth. By destroying his power, Travers was able to become his true self, while also unlocking the dragons of Earth, and the other isles of Namira as well as restoring some of the lost races there.
The only alternate that Jokaz had, this one locked in The Garden (Gai's Universe) instead of the Milky Way. Zikary had come with The Vyadajol into The Garden, and so his death unlocked that universe, but brought the Vyadajol to Earth with Travers for guidance and to help him figure out how their universe worked and was named, so he may save the planets all.
