Arena Map: Caves

Hey all. I'm working on a little project and I was hoping for a quick answer to this - what caves are used in the Arena Cave map? Oranbega caves?

Thanks!

Thought they were just the tunnels. The larger ones, not those older, cramped caves.

Ah good to know. Does anyone know about the AE Circle of Thorn maps? If it's the Oranbega map?

Edit - Ah I found that you can unlock them. Nevermind!
