Produce a detailed written description of a eerie scene inside of a cave with murk, fog, corridor, and walls.

The corridor splits into three passages, all similar in appearance. The murk makes directions seem non-existent, and the low-lying fog creates a slowly revolving vortex in the center of the tangents. Every so often, the stone of the walls, floor and ceiling emits a low rumble, as though complaining of trespassers within its arteries.
