Magister Surdiel

Magister Surdiel is a Wintergrasp battlemaster that can be found in Sunreaver's Sanctuary in Dalaran.

When the battle of Wintergrasp starts, he will teleport players to the battlefield, and upon Horde victory he will create a portal for quick travel to Wintergrasp Fortress.

Mists of Pandaria
During the Purge of Dalaran, Surdiel was held captive by the Silver Covenant at his usual spot within Sunreaver's Sanctuary. On Rommath's orders, he was freed by a Horde adventurer and expressed hope that he could find work in the Horde. He safely returned to Silvermoon City.

Trivia

 * Magister Surdiel was originally stationed at the front of the Wintergrasp Demolisher alongside the Horde Warbringer and High Arcanist Savor, though due to the small amount of space in that particular hallway he was relocated to the larger inner sanctum, and the various battleground portals were placed around him, as opposed to the spot he now resides in.
 * At some point, Magister Surdiel would periodically announce the upcoming Wintergrasp battle via yells heard throughout Dalaran. The frequency of these yells grew much to the annoyance of many players and an addon was even developed to block them out, though these yells were eventually removed.
