Is Iceland part of supreme vikings?? are the one??

I think this question is asking whether there are active members of the "confraternity" in that country OR if the SV group considers Iceland to be part of their "domain." Paganism as a game...

Whether this extends into "fantasy reenactments" is a fashion similar to the Society foris Creative Anachronisms (SCA) or Star Trek role playing is unknown to me.

As far as I can make out, we are talking about a community of gamers. The question might be addressed on the facebook page of the organization. I would be hardpressed to find an authoratative source of information.
