Bel-Hathor

Bel-Hathor the Sage was the tenth Phoenix King of Ulthuan, and third to originate from Saphery. He would later be succeeded by Finubar into the present day.

History
Once again the Asur found themselves leaderless during a time of war. The clear candidate, Mentheus of Caledor, was dead, and none could agree on a suitable replacement. In the end Bel-Hathor, a wizard prince of Saphery was chosen and crowned. He was chosen because many in the Elven court believed that he could easily be manipulated to their own ends. They were proven wrong, and Bel-Hathor became a ruler as famed for his resolve as for his wisdom. The most notable example of this was his refusal to agree to an invasion of Naggaroth: while he was aware that the High Elves could likely destroy the Dark Elves in their weakened state, he feared that such a bloody and bitter war would leave so many dead that the extinction of the Elven race would be assured. He would not gamble his people's future simply for the satisfaction of revenge.

After many years of raiding by Norse tribes, the Elves began to hear of the human Empire in the Old World, and became uneasy. Bel-Hathor decreed that no human would be allowed to set foot on Ulthuan, but sent Finubar of Lothern to investigate what had become of the Old World in the Asur's absence. Finubar sailed to the Old World and found that the humans had some measure of civilization, and rediscovered the Asrai of Athel Loren. He opened relations with the Empire, Bretonnia and even the Dwarfs. He returned to Ulthuan with his knowledge and Bel-Hathor revoked his decree, causing trade to flourish. After 548 years of rule, Bel-Hathor the Sage died peacefully.
