Set in Stone  

'Battles ebb and flow, Spider. We fight war as we can and with the weapons at our command. One such weapon are the trolls. As strong as they are stupid, massive as they are clumsy, and killing machines unmatched! With their benefits come drawbacks.

'The largest is their penchant for smashing walls apart. Holes in the wall mean that an enemy can easily breach our forces, so we must repair those holes. But the trolls pound the stone to dust and we haven't the numbers to dig a quarry here in the Ettenmoors, so we use the trolls.

'How, you wonder? Ever seen them in the sun? Solid as the rock from whence they were first drawn. The Coldeve-trolls wandering throughout the Ettenmoors often get caught in the sun and die. Chip away their stone and return it to me for repairs.'
