Kama finds 25 silver and 12 gold on the Hobgoblins, but nothing else.
In the room that the hobgoblins came out of (Northwest corner) you find four plain straw pallets and bedrolls are lined up on the floor of this barracks. Brackets on the walls hold a number of weapons - spears, swords, morningstars, and more. The north wall shows signs of damage, but the floor is swept clean of rubble.
Making her way around the castle, a little ways to the East Xora finds a canvas covering part of a broken tower (North Center). This tower has almost completely collapsed, although the ground floor still has a little open space. Rotting crates and ancient barrels show that provisions were once stored here. A heavy curtain blocks a crumbling area to the south, and an intact door leads east.
Continuing her way around, she doesn't find another entrance until she reaches the door on the south side of the building.
Further along she finds that the southwest tower of the castle is little more than a heap of rubble. Several ragged bedrolls are scattered across the remaining floor space, and a small, twisting passage leads east through the ruins.
On the West side a short flight of steps leads up to a terrace in front of the main entryway. Past the wreckage of a pair of sundered doors lies a shadowed hall. Round towers loom over the entranceway, with dark arrow slits looking down on the terrace.
OOC:
All of this is assuming that Xora merely scouted the outside and didn't enter.
