NIFELHEIM

Tyrant and Hellbutcher are twins, and are known in Sweden as "Bröderna Hårdrock", which translates to "The Hard Rock Brothers", after a documentary about heavy metal fans was broadcasted in 1998. Parts of the documentary were used by the insurance company Trygg Hansa as TV ads. Tyrant's and Hellbutcher's real names are Erik and Per "Pelle" Gustavsson.

Nifelheim participated in the Bathory tribute "In Conspiracy With Satan", released by Hellspawn/No Fashion Records in 1998, covering the song "Die In Fire".

In Norse mythology, Nifelheim (or Niflheimr) is a realm of coldness, ice and mist. It was believed to be the realm of the dead, those who did not die in battle, and it is ruled by the goddess Hel.
