I'm surprised no one has brought up the HW armorer quests, as that was all about creating armor for an adventuring party. You help them out after they save another member of the armorer's guild who almost gets killed by a rat while learning to adventure.

My question though was more in the SB carpenter quests, how am I building furniture for an NPC adventurer in Lavender Beds? He'd better be in the Lilly Hills apartments.
