The Sunwell and the end of Quel'Delar's exile await, <name>.
You will find Lor'themar Theron, the regent of Quel'Thalas, and Grand Magister Rommath standing within. Be wary of them and do not allow them to entrap you in their political scheming.
Instead, remain focused on your task here. Immerse the reformed Quel'Delar in the Sunwell to complete its restoration, then show it to Myralio Sunblaze at Quel'Delar's Rest. Speak to a Warden of the Sunwell when you are ready to enter the Sunwell Plateau.
