I played Bilgritik, dwarf shaman in Outlander.

There are also logs on the other board of one of the key events that transpired to get in. It is also referenced as one of the most epic moments in CF history, if for nothing else the irony of the final blow (Search for the name).

To expand on the rest of your question,it is possible, but I was told I would probably be the only dwarf, so take that for what it's worth. Current outtie Imms are different from who brought me in. Also, I had a role that really tied into Outtie lore. Nothing from keeping you from trying with other races, but some may be far harder (azure) than others (goblins maybe?)
