Investigating to the north, we find a guard room full of hobgoblins. Strangely enough, these creatures are not ready for combat - perhaps the battle hasn't been as loud as I thought. The hobgoblins are fairly easy to defeat, and while they have no equipment of interest, the rooms have a few useful weapons, along with what must be Sildar's equipment.
Moving east, we discover (surprise, surprise) yet more goblins.
