[@Haru Nyan] all supernaturals acceptable! Beyond The Gate is basically the entire world's collection of magical creatures (with a few stragglers and exceptions) pushed off the edge of the world. Near anything is possible.  There may be adjustments if abilities are too powerful, but basically make whatever type of character you want to play and I can help balance it if needbe :D 

Also some magickal creatures may have slipped through and lived in the human world - or been created there. Creatures like changelings or creatures that are created/fed by human emotions, for example. Often these creatures get found out and shipped back to World's End, though some may never be discovered.
