Michael - A member of the Avalon clan.
His egg was laid in the Wyvern Clan rookery in 988 and was due to hatch in 998. Due to the Wyvern Massacre however, Princess Katharine, the Magus, and Tom were forced to take all the rookery eggs away in 994. The next year, on September 28th 995, they took the eggs to Avalon. Because of the difference in the flow of time there, Michael did not hatch until 1058.
Princess Katherine, the Magus and Tom raised the "eggs" as their children and Michael grew up on Avalon, with his rookery brothers and sisters, in peace and isolation from the world.
Real World Background
Michael was named after one of the four great Archangels of Judeo-Christian lore (the other three being Gabriel, Raphael, and Uriel).
