The group passes through the door they enter not another room, but another corridor. Seems this place is full of them. As you twist through the passage you begin to wonder if this was ever a functioning sewer, or more a long forgotten tunnel system used for other means.
The short corridor intersects into another short hallway; the north end turns to the west for only a few feet before turning back to the south and leading to another door, while the southern end turns to the east and extends on for some distance.
As Rogash peers down the long eastern corridor he spots some movement with his darkvision. It appears to be a kobold, and it is clearly dazed. It spots Rogash through the darkness, and its eyes open as it lumbers forward.
Zombie--the dwarf's first thought. The thought is quickly put to rest, however, and Rogash begins to tremble just a bit. As the bewildered kobold lumbers through the corridor, it reaches out with empty hands, its eyes are wild and its mouth hangs open stupidly. The thing lets loose a wince of pain as its left foot seems to melt up to the knee and then reforms on its next step.
The lone kobold is about 40 feet from Rogash.
