Starofash

In early March 2006, Peccatum announced their end leaving more time for their own individual projects. In October 2006, Tveitan announced a collaboration with the Japanese author Kenji Siratori. Siratori provided lyrics, spoken word vocals and the music video to the track "Neo Drugismo", which appeared on the second Starofash album The Thread.

In 2000, Starofash performed at the Mystic Art Festival in Poland, along with the Inferno Festival in her homeland of Norway in 2001. It was also in 2001 that Starofash was signed to Jester Records. The project's first album, called Iter.Viator, was released in 2002, and it featured various guest artists. Among them are members of Emperor and Ulver.

Heidi S. Tveitan was first introduced to music after taking singing and music lessons for many years. In 1998, she formed Peccatum with her husband Ihsahn and brother Lord Pz. Shortly after in 1999 Peccatum was signed to Candlelight Records and the first Peccatum album Strangling from Within was released. This was soon followed by an American and European tour. Tveitan claimed to work well musically in a "husband and wife" situation.
