Iron Savior is a heavy metal band formed in Hamburg, Germany in 1996. It was formed by Piet Sielck (Savage Circus), Kai Hansen (Helloween, Gamma Ray), Thomas 'Thomen' Stauch (ex-Blind Guardian, ex-Savage Circus). Both Sielck and Hansen handled lead vocal duties, Sielck doing the most parts and was also the lower voice and Hansen the higher and sang occasionally. The band has a science-fiction theme to their writing. Most of their songs narrate an elaborate story based on a plot involving a self-aware space vessel (the Iron Savior) constructed by the lost continent of Atlantis.
