Speak with Shadow Priest Sarvis at Deathknell in Tirisfal Glades.
Are you still here, <name>? You know, I'm only a deathguard. I don't have many tasks I can hand out to passers-by like you.
I'd recommend that you talk to Shadow Priest Sarvis. I remember, he helped me get on my feet after I was plucked out of that tomb. I'm sure he'll do the same for you.
You'll find him just inside the chapel, here on the west side of town.
