Prince Nallorath (also called Nall by his friends) was a high elf prince 2600 years before the First War when the demons started attacking Dalaran. He was the best friend of the half-elf Alodi. Nallorath was also a mage, and he may be part of the Sunstrider Dynasty.
Council of Tirisfal members Ethylar and Rohar were magi at his father's court, while Aertin Brighthand used to be. He did not know of the Council, nor of Ethylar's, Rohar's, and Aertin's connection to it.
