Ah, no sorry perhaps not clear. What I meant was to caves as say forest is to trees. So if I have a dungeon level of caves with say smoke in them I could call it THE WHATEVER OF SMOKE. That sort of thing.
http://www.cave-exploring.com/Definitions.htmGo from there...The Traverses of Smoke? Well, maybe you'll find something better...
Traverses might work! Cheers.
