Start NPC: Arthgal
Lamya has infiltrated the tunnel and probably needs help down there.
I didn't want any soldiers going solo, but she wouldn't listen.
Find her and see what she needs help with. You may want to hurry.
Huh. Well, I didn't need extra help, but I suppose you'll come in handy.
As long as you're ready to work.
Find Lamya in the southeastern Halls of Utterdark.
