Part 1: Goblin Arrows

Bug is about to proceed further into the cave's north tunnel when he turns around to remind his new companions to come running of he calls for help and realizes something "off" about the rubble in the cave he's been kept prisoner in. Some of the debris on the ground is rocks and detritus from outside, but he also notices that along the east wall, much of the material on the ground is more rubbish than natural mineral, including what appears to be cooked animal bones, scraps of parchment, bits of rusty metal and threadbare cloth, and other refuse.

Looking at the pile of materials on the ground in better light, you see it is indeed rubbish. Noticing claw marks and scratches at the edge of the refuse pile, it appears the garbage had been picked at by the wolves at some point, though their chain leashes were too short to reach bug or the garbage before they died. The refuse appears to have been dropped into this room from somewhere above through a natural chimney-like fissure in the stone. The light from Osvaldo's torch reveals that the chimney ends after 30 feet above, though what room or passageway may be beyond is unknown. By the looks of it, it can be climbed easily enough using natural stone handholds (and a few successful Athletics checks) though it may take some time and if one were to fall from close to the top there would be a 30' fall to try and walk off afterward. Otherwise, there's still the tunnel heading north just outside of this room.

Severus and Osvaldo watch as the gnome scurries up the chimney. Darkness seems to engulf him the higher he climbs, though Osvaldo's torch keeps him illuminated enough to observe. The gnome deftly ascends and after about 30 feet you see him come to a halt, evidently assessing the situation.

"TOMORROW'S DINNER CLIMBS UP KLARG'S DIRTY-HOLE DOES HE!?!"

Whatever the agile gnome has found above, he's been spotted, and by something large it seems by the booming voice that shouts from above.
