Speak with Mennet Carkad in the Rogues' Quarter of the Undercity.
<name>? Not quite what I was expecting, considering Carkad himself has taken an interest to you. Looks can be deceiving though, right?
Either way, you should go see him as soon as possible. You wouldn't want to know what happened to the last few that chose to ignore his summons.
Hm. No doubt you made your way here at first mention of my summons, yes? Of course. I would expect no less from a prospective Deathstalker.
