I have two assumptions, and I am going to laugh my AO if I'm right on both. I read all the posts so this info might already be here but I just overlooked it mixed in with all the other ridiculous junk.
1) The Dominatixes...Dominatrices, Dominatricii, whatever the name of this thing is going to be - are a Clan guild.
2) They are an RK1 guild.
And for extra credit, I suspect that Hypnotia is actually Howard Stern playing a joke on all of us.
(Yes, I'm casting aspersions on the clan guilds and on RK1 - just my opinion and experience with both, figured why put out the fire when I can fan the flames on this hilarious 'looking for members' thread).
