Zyklon was formed around 1998 by Emperor's Samoth (guitar). Trym (drums), who was also of Emperor, was soon asked to join. The two of them wrote material same year, but wasn't able to record anything until 2000. It was then that Destructhor (guitar) from Myrkskog joined the band. They could finally record their written material and in 2001, "World Ov Worms", their debut LP, was released. It was produced by Thorbjørn Akkerhaugen in Akkerhaugen Studios and featured Daemon from Limbonic Art, who became a permanent member afterwards, and Fetish queen Persephone. All lyrics were written by Bård "Faust" Eithun.
After getting a record deal with Candlelight Records, they hired a bassist, Cosmocrator, for live shows and recorded "Dominate" for the Morbid Angel tribute album. Daemon eventually left the band and was replaced by Sectdamon (vocals, bass), who was also of Myrkskog. In 2003 the band released "Aeon", which showed that they were heading towards Death Metal.
