Erik, whose last name is unknown, goes by under the moniker of Vrolok. Previously he played in Chaos Predicted and Gorgoroth. He joined this last band after Grim (real name: Erik Brødreskift) had left in 1979. Around 1998 Vrolok decided to leave. He was replaced by Erlend "Sersjant" Erichsen.
Erik also played in Aeternus between 1993 and February 2006, when he decided to quit a while after the Production of "HeXaeon" was completed.
