I'm not really sure of the "Man", but I think it has something to do with a hebrean word "adam"...

Really, that should be quite easy to quess.
Scandinavians will propably know this, but for others this might be new:
Jotunheim and Vanheim are simply Jotun Home and Van Home. In fact Jotunheim is near some sort of Glacier in Sweden (or then not, my memory has done me ugly things before).
Pythium comees from Pythia, which was some kind of a god/dess, IIRC. Also I think it means snake.
Marignon is pseudo-french, or atleast I think it is.
Ulm exists, it is a place in Germany. The intelligence of Ulmians, or lack of it, is joking matter in Germany, or so I have heard...
Machaka seems to be the sound produced when you whack people with long sticks with a blade in the end.
Mictlan is pseudo-aztek, I think.
Caelum and Abysia come from Latin, from the words meaning Heaven and Hell. Or maybe High and Low, or some such, but you get the idea...
Pangaea is the great continent that existed when earth was young, and has then broken to Europe, N&S America etc.
Most know Atlantis, the mystical continent that supposedly went down to the bottom of the Atlantic. (better wording, please)
T'ien C'hi propably means something. At least Google finds 3000+ pages...
And R'lyeh comes from Cthulhu mythos created by H.P. Lovecraft, man who didn't believe to thepower of names...
I have no idea about C'tis, Arcoschepale or Ermor.
Okay, or from Machaka. But that wasn't bad quess,was it?
EDITed 3 times: only for typos! I should learn to preview my Posts first!
