You are at where you are in a foreboding scene outside a chasm with a river and a silver ribbon.

A torrent erupts from the face of the plateau several hundred feet below. Clear, sparkling water pours out of a chasm and cascades to the low mountain range below, drifting off to the southeast as a silver ribbon. Though the river appears to provide ample water, no trees dot the river's edge as far as the eye can see. The chasm itself yawns before you a hundred feet wide, effectively blocking progress along the plateau's edge to the west.
