Gerrol's Wife - NWN Side Quest (Chapter 2)

North Road: Gerrol's Wife is a side quest that begins in either Port Llast or in the North Road depending on who you talk to first. In Port Llast you'll be approached by someone named "Farmer's Son" immediately after leaving Kendrack's Barracks for the first time. If you go through his dialogue you'll start this quest at that time.

Alternatively, you can also start this quest by speaking with Gerrol on the North Road map, you'll find Gerrol just outside the gates leading in and out of Port Llast. Talking to Gerrol will also start the North Road: Dergiab's Head side quest which takes place in the same area as this one.

For this quest you'll have to enter the caves in the northern portion of the North Road map. There are numerous cave entrances here and they all more or less lead to the same cave system. You can find Gerrol's Wife Leah in the Bugbear Caves which can be reached directly by entering the northwestern most cave on the North Road map or by traveling through the Goblin and Orc Caves and going down the stairs.

Leah is being held in a cage in the central portion of the map, as shown in my screenshot above. Free her from the prison for some EXP and then send her home so you can complete the quest the next time you speak with Gerrol. That's all there is to it!
