Ildjarn was a raw black metal solo project from Norway that formed in 1992. Ildjarn recorded music until 1997 but did not officially end until 2005. The man behind Ildjarn was Vidar Vaaer, although some releases were collaborations with a musician known as Nidhogg. Of all the released music, the only Ildjarn song to have its lyrics published was Eksistensens Jeger, from the self-titled Ildjarn-Nidhogg compilation. Ildjarn, along with fellow comrades Ihsahn and Samoth of the local Telemark area (Norway) formed the band ‘Thou Shalt Suffer’.
