Arckanum was a Swedish black metal solo band formed in 1993 by Johan "Shamaatae" Lahger, who was the only constant member.
[2] On leaving Grotesque, Shamaatae formed a technical death metal band called Disinterment, who recorded one demo and played a few gigs before splitting up.
[2] After several releases, by 1998 Shamaatae had discontinued working with Necropolis Records because they went under, and turned his attention to writing books on the subjects of Pan, Old Norse traditions, runic witchcraft and anti-cosmic Satanism/chaos-gnosticism.
[2] Antikosmos and ÞÞÞÞÞÞÞÞÞÞÞ featured the guest appearance of Set Teitan of the bands Dissection and Watain.
Arckanum was split up in 2018 in order for Shamaatae to focus solely on his authorship and spiritual ventures.
