Caledor Dragontamer was a High Elf of Ulthuan, and its greatest mage during the reign of Phoenix King Aenarion. In the time of Aenarion, Caledor Dragontamer was a chief ally of the Defender's, and a leader of the Asur. He and the rest of the Archmages sacrificed themselves to banish the Chaos energies from the Old World, and are currently trapped in the magical Great Vortex that keeps the energies at bay on the Isle of the Dead, unable to die, unable to free themselves without undoing the work they wrought.
