It entails Viking battles with real steel weapons we train with, we train to look like we are really hacking people to pieces but pulling our shot to stop your axe cleaving someone's head open... that said we have had broken bones already xD but it is really good fun!
On another note you have the living history, which is basically just living in the Dark Ages exactly how the Danes, Saxons etc lived in the 7th-10th century
Everyone has professions for example I am a metal caster making pewter, bronze and silver jewellery. Blacksmithing, Weaving, cooking, Coin striking and shit loads more =]
id suggest to anyone that has a re-enactment group nearby to join them! massive life changer plus you have the bonus of surviving in harsh circumstances... like no internet! No decent food! no electronics, no communications just fire, blood, violence and most of all death.
