I managed to find a relic Geson's bow, but I can't find the string to have it made complete and usable. Anyone know where I can find it?

well can't tell ya exactly where, cut I don't remember, but its somewhere between spellhold and the underdark I believe(least I'm pretty sure i didn't have it before I left the mainland). Hope that helps ya a bit

The string is in a chest in the asylum labyrinth. Guarded by 3 golems.

Don't Quote me on this, but it's either from the Red Dragon lair Firkaag? or the Underwater City, I think

I'm currently dealing with underdark and recently jst finished the underwater quest. I think the string is most likely to be found between those two. If I remember correctly... it's the rope from the treasury that will transform into the string after u have used it to access underdark (after u helped the Sahuagin Prince). I might be wrong though

Survivor is correct, it is located in the Asylum Dungeon. For the *exact* location, you can check out our walkthrough at http://www.gamebanshee.com/baldursgateii/

Hope this helps.
