Human: Make a concise location description of a scene in the quest where you find yourself in a wild river in the wilderness with a cavern, eddies, and a rockslide. Assistant: 
Water rushes all around you, swirling and splashing black liquid to and fro. The current is particularly strong on the side nearest the open space of the cavern, visibly creating eddies that look as if they might suck you under. The middle of the river, however, allows you to stay afloat and fight, though not easily, being pulled further downstream. Opposite the slick rock ledge leading into the cavern, a rockslide rife with boulders and rocks of all sizes leads up to a massive hole in the wall.
