There should be Great Old Ones in Gothador! Of course, the Mighty Cows could call the race 'Transdimensional' or 'Extradimensional', or even 'Multidimensional', but those of us "in the know" would...well...know that they were Great Old Ones. Version 1 (Male/Female) could be of the...erm...Squid variety, and Version 2 (Male/Female) could have kind of an...amorphous...form or something.
And just use your imagination regarding the kind of creature it would have as its summons...
I know it sounds like I'm joking, but I'm serious. If I had thought about it all those years ago 
(feels funny to type that) when we got the Shadow Class, I would have suggested it, but I wanted a Dwarf Class so bad my teeth hurt.
I know it'll never happen, but imagine how awesome they could be. I'm picturing an Amorphous variety Miner right now...almost like a gigantic Horta. 
How much fun Doc might have had doing personalized Avatars for those...
