As a young prince in the days of Bel-Hathor, Belannaer vainly sought to find the entrance to the White Tower. Only when he despaired and turned back to find wisdom on his own did the tower allow him passage. He studied there for a long time and became the favourite pupil of High Loremaster Cyeos.
Belannaer was one of the mages that shrouded the coasts of Ulthuan with a maze of spells and repaired the waystones damaged by Grom the Paunch. He also was a companion of Finubar on his journeys to the east, and the tutor of Teclis. When Teclis left the White Tower to search for his brother, it was Belannaer who convinced Cyeos to give him the War Crown of Saphery.
