Cellador is a power metal band based out of Denver, Colorado. Originally from Omaha, Nebraska, the band was founded in 2003 by Chris Petersen, the band's primary songwriter, as a direct contrast to the overcrowded metalcore and death metal scenes of the American Midwest. The band has had multiple lineup changes since its inception, but is now rounded out by bass player James Pickett, drummer Nick Mccallister, keyboardist Diego Valadez, and guitarist Caleb Delaet. In 2005 the band signed to Metal Blade Records after playing a show with The Black Dahlia Murder.

Cellador's debut album Enter Deception was released in 2006. The band recorded the album at Erik Rutan's Mana Studios. In an article from the December 2006 issue of Metal Maniacs magazine, Chris Petersen says he created the band name in reference to a J.R.R. Tolkien essay which stated that the two words have an appealing sound when combined. Petersen also said that the band was originally called "Apostate", but the name was later changed to Cellador because he felt it was more fitting for the band.
