A "Berserker" was a Viking warrior who fought with wild ferocity. In the berserker fighting tradition the warriors take on the spirit of bears whilst foaming at the mouth and gnawing on the edges of their shields. It is the source of the Vikings' reputation of ferocity.
I don´t expect any battles tomorrow, but the dancing will be ferocious I am sure!
As for the theme, I have the most wonderful helmet from Gryphon Lair that should work well, but not much else. Hmmm, I wonder if I dare go to the party only wearing a helmet...?
