Anglo-Norwegian Black Metal collaboration CODE, based in Oslo, was initially fronted upon formation in 2002 by DHG and VOID vocalist Kvohst (a.k.a. Mathew McNerney) and featured bassist Viper ('Vicotnik' / Yusaf Parvez) of VED BUENS ENDE and DØDHEIMSGARD and former ULVER and VALHALL drummer Aiwarikiar (Erik O. Lancelot). Subsequently, second guitarist Vyttra was installed.

Finnish label Spikefarm released the debut album, 'Nouveau Gloaming' laid down initially in Savonlinna in Finland but completed at Skrek Og Skru in Hells Fire Oslo, Norway with producer Henning Bortne, in May 2005.
