Thornium was founded by Thyph (a.k.a Thypheuz) in 1993. Thyph entered the studio the same year to record Thornium´s first and only demo “North Storms Of The Bestial Goat Sign”. It contain three songs: “In The Depths Of Northern Darkness”, “North Storms Of The Bestial Goat Sign” and “Min Vandring Till Mörkrets Furste”. All instruments was recorded by Thyph himself starting with the drums, then the guitars on top and lastly bass guitar and vocals. With Thyph having an extensive net of contacts in the Black Metal underground at that time the demo was very well received all over.
