Usually dressed in an elf, troll, or goblin costume (sometimes complete with bat wings and skull codpiece), the mysterious Mortiis was an indispensable force in the genesis of Norway's epic Viking metal sound. As the original bassist of Norwegian black metal pioneers Emperor, Mortiis was credited with stimulating the group's interest in blending furiously chaotic black metal with haunting synthesizer melodies often based loosely on Norwegian folk, thus laying the groundwork for a sound that would dominate underground metal over the next decade. However, for all his impact, Mortiis was only with the group for a very short time; he played on their 1992 Wrath of the Tyrant demo, a split release with Enslaved titled Hordanes Land, and a 7" single, "As the Shadows Rise," but never an official full-length album. Mortiis left Emperor rather abruptly in 1993 to pursue a solo career; still only 18 years old, he moved to Halmstad, Sweden, where he formed his own Dark Dungeon label. His 1993 solo debut, Født Til Å Herske, was a surprising departure from Emperor's relentless intensity, and in fact from guitar-oriented music altogether; instead, Mortiis worked primarily with electronic instruments, creating a sorrowful, sinister ambience with more than a hint of goth rock. Ånden Som Gjorde Opprör followed in 1994, as did the first of several side projects: a more industrial-tinged group called Vond, who issued an album titled Selvmord (later released in the U.S. as Slipp Sorgen Los). 1995 brought another new Mortiis album (Keiser av en Dimensjon Ukjent, or Emperor of a Dimension Unknown) and another side project, this one called Fata Morgana, who issued a self-titled debut. In 1996, Mortiis recorded a limited-edition series of five 12" EPs, whose material was subsequently collected as Crypt of the Wizard; 1997 brought yet another side project, the somewhat lighter Cinticele Diavolui.
