Nostalrius Begins - Quality wow vanilla realm (1.12)

how to complete the quest chain " missing diplomat " to get a ring and gold, after winning Handel.

Go back to Theramore and enter the big tower you see just when you enter it from Dustwallow Marsh. Go upstairs all the way to the top to find a guy to turn in your quest. Then you get a quest to talk to Jaina Proudmoore and get your ring.

For looking up questlines online go to http://db.vanillagaming.org and search for your quest there.

I did the whole chain of quests , but trevosh not given me the task to talk with Jaina , but instead over his head a blue question mark.
