Use the lasso

Nora threw the lasso over the dead Morlok's head. She impressed herself with that throw, getting the lasso to tighten around the neck. With a pull the pole the corpse hung on snapped, sending the body tumbling over the edge. However due to the lasso she was able to keep the body from falling into the abyss, and safely managed to pull it up onto the bridge she was standing on. She pushed the white hair matted with blood to the side, revealing the shining object that drove her to pull this corpse down in the first place. It seemed to be some kind of golden mouth-piece to a musical instrument, like a horn or flute. There are two slots on the inside rim that seemed to be where presumably the next piece would attach to.

Nora pocketed the golden mouth piece.
