SGA= Star Gate Atlantis, a sci-fi TV show. The "bad guys" are aliens called Wraith. They also happen to have long white hair, wear long black leather coats have cats/reptile eyes and are very cool!

However, long before SGA Wraith were even a glimmer in a make-up artist's eye, Wraith Wolf was my magical name way back in my 20s when I used to be a practicing Pagan - and for pretty much the same reasons you mention... a lone wolf apparition scouting around the outskirts, part of me not really wanting to join in, but part of me angry that no one asked me to!
