Council of Tirisfal

The Council of Tirisfal (Order of Tirisfal, Order, or Tirisfalen) was the secret council of high elf, gnome, and human mages charged with the selection and disposition of the Guardian of Tirisfal.

The Order was formed by the most powerful of the high elves in order to prevent and safeguard Azeroth from the demons, something that their Highborne ancestors couldn't do. They derived their name from their meeting place in the Tirisfal Glades.

History
Over 3,000 years ago the elven ruling council, the Convocation of Silvermoon, that had long ago sworn to forestall any full return by the Burning Legion, met secretly with the most powerful wizards of the human nations to discuss the threat of demonic incursions. The ancient ethereal barrier that warded off the Legion, erected by the high elves during the foundation of Quel'Thalas, was not impenetrable; as long as arcane magic was wielded the demons would forever be drawn to Azeroth to find gaps in their defenses. The summit of elves and humans brought about the creation of The Order of Tirisfal. The Order's quest was to hunt those demons who had already arrived and prevent others from entering Azeroth.

For a great period of time, the Order's oldest members were three high elves, among them Relfthra. They were in a position of authority even during the guardianship of Scavell, and up until the purge of the Tirisfalen.

The two most famous Guardians of Tirisfal by far were the last two — Aegwynn and her son Medivh. Medivh/Sargeras killed many named and unnamed members of the Order throughout Azeroth during the time of the First War, before he was slain. It is, however, known that Aegwynn revived an uncorrupted Medivh, so theoretically he still lives. While it may be possible for Medivh to pass the mantle of Guardian to another, it was he who destroyed the Order with the specific purpose of breaking the chain, the one thing he and Sargeras agreed upon. His final known speech echoes this sentiment, as he wished to teach the world that it no longer needed Guardians.
