Black Spider

Nezznar, a male drow left the underdark on the orders of priestesses of Lolth with the aid of a spider staff and two dopplegangers. A former slave, he was looking for the cave to gain weapons and armour to secure his survival. He was concerned about the "evil to come".

Some correspondence was found between Iarno and the Black Spider pertaining to the fact that the Black Spider was aware of mysterious strangers entering town (the party?) and tasking Iarno to capture them and find any dwarven maps that they might have.

Lord Albrek

''My spies in Neverwinter tell me that strangers are due to arrive in Phandalin. They could be working for the dwarves. Capture them if you can, kill them if you must, but don't allow any of them to upset our plans. See that any dwarven maps in their possession are delivered to me with haste.''

I'm counting on you Iarno

Do not disappoint me
