Well, after having a nice chat with TorGal in the cellar, I noticed something. I always thought he was talking about himself when talking about stronger or something, but I'm beginning to doubt. Who sent those trolls? Who's stronger? Who's evil butt needs to be kicked?

you'll know once you've defeated the trolls

Well, not immediately, but some time later, if I'm not too much mistaken.

I am a Paladin & I normally always drop Nalia after the quest, so I don't know if I'll find out.

yeah, really. I've never figured out if it was the Roenalls, but i don't think so, even though they do show up pretty quickly afterwards. It almost seems to me like it's the Twisted Rune. they seem to be behind all the other nasty things going on. (Skinner murders, slavery, and other bad stuff)

More info will be appreciated. I've had Nalia in my party since the beginning, and am right about to go for spellhold, and i STILL haven't figured it out! Do you have the Twisted Rune patch? It says something about how Nalia is an integral part of it, but she hasn't done anything yet.

Nalia does get another quest, but it will only initiate on the mainland, meaning that if you take off for Spellhold now, you won't see anything until you start Chapter 6. (This is true for all the other NPC quests, as well. Once you start Chapter 6, be prepared for a swarm of Messengers and the like, running up to you to tell you what needs to be done.) If you haven't gone to Lord de'Arnise's funeral yet, you'll be summoned there. A few days after that, something else will happen. ;)
