Keiser av en dimensjon ukjent

Keiser av en dimensjon ukjent (lit. Emperor of a Dimension Unknown) is the third full-length album from Norwegian solo artist Mortiis, which was released in 1995. It initially came on a golden CD, whereas the LP was a picture disc wrapped in a giant poster. This album was limited to 500 numbered copies. The LP was reissued for the US by The Ajna Offensive, with new artwork. It was limited to 300 copies, also coming with a booklet. It had previews of the then forthcoming book Secrets of My Kingdom.
