He announced that the tentative name of the album will be Thulêan Mysteries, which will have 23 songs. The tracks from the album were previously used as background music on Vikernes' YouTube channel, which was taken down the same year. On 18 December, Vikernes tweeted the album cover for Thulean Mysteries and announced its release date as 13 March 2020. The image on the upcoming (03/2020) Burzum album 'Thulêan Mysteries' is by Th. Kittelsen. It's called "Nøkken" (English "Nix"/"Water Troll"). "Nøkken" derives from Norse 'nykr' & translates as "stench". This is of course a mythic creature, that can be found & fought in MYFAROG. "Thulêan Mysteries was made passively, in the sense that I never intended to make a new album; I just made music every now and then and at one point realized that I actually had enough to release it all on an album. When asked to do so I figured: why not? It was a good idea. The music is a little bit of this and a little bit of that, transcending any genre, and perhaps belonging to many different genres. The intention with it was always to create a certain atmosphere, often related to an idea or a situation. Since my true passion has never been music, but actually tabletop role-playing games, I figured I should make this an album intended for that use; as background music for my own MYFAROG (Mythic Fantasy Role-playing Game). Hopefully you will get a sense of Thulê when you listen to this, like always with Burzum, ideally when on your own. I hope you will enjoy this soundtrack to Thulê, to Mother Nature and life itself" - Varg Vikernes
