After reaching level 74, you can see the new quest "Magic Kingdom of Dalaran" in the Borean Tundra, Howling Fjord, Dragonblight or Grizzly Hills camp. Accepting this quest will give you a prop "Ring of the Kirin Tor Emblem". At this time, if you talk to the NPC, you can be teleported directly to Dalaran.
If you keep this quest, you can reuse these NPCs to teleport to Dalaran.
