After much observation, I have discovered Morganth's plans.
He searches for the Scythe of Elune...and he may have found it! If he has, then the Redridge Mountains, and the kingdom of Stormwind, will soon feel his dark might.
I am not prepared to pit myself against Morganth, but I fear he must be dealt with now. So you must enter the Tower of Ilgalar and face Morganth.
Defeat him, and bring me his Pendant of Shadow. Do this, and the kingdom will owe you much.
Hurry, <name>, before my fears of Morganth spreading his power are made real!
You have done well, <name>. In defeating the warlock Morganth, Stormwind is saved from a grave peril.
I offer you this reward most humbly. And I would bid you peace, if these were peaceful times.
But instead, I will bid you luck with your trials, and victory in the conflicts ahead.
