Dear administrator, I can't see the NPC of MAGE tower challenge, but I can see this task on the map. How to solve it? Thank you very much.

Hello. To pass the trial itself in the Tower of the Magi, you need to pass the prequests for it. The quests start at Cadgar in the new Dalaran, where the Amethyst Citadel is. After passing it you will get access to the Tower of the Mages.
