Führerhauptquartier Wolfsschanze
By early 1994 Hellhammer, Maniac, and Necrobutcher had reformed the band with new guitarist Rune Eriksen ("Blasphemer") in place of Euronymous. Despite arousing some controversy and scepticism for reforming without founding member Euronymous, the group returned with the 1997 "Wolf's Lair Abyss" EP.
