Antonidas was the teacher of Jaina Proudmoore and the leader of the Kirin Tor.
As a young boy, Antonidas became an apprentice of the Kirin Tor. He studied further until he became 12 where he earned the admiration and respect of his master.
The Prophet later came to Antonidas for aid in Kalimdor. He ignored the aid and turned his attention to defeat the undead in Lordaeron. His apprentice Jaina however listened to the Prophet and faced the Burning Legion. Antonidas led the defense of Kirin Tor against Arthas Menethil who became a Death Knight. Despite his valiant efforts, Antonidas was killed by the knight but was remembered by his fellow mages as a hero.
