Iron Savior is a German power metal band that was formed in Hamburg in 1996. Following a period of several years working behind the scenes in music production, multi-instrumentalist and producer/engineer Piet Sielck joined with former Helloween bandmate Kai Hansen and then-drummer for Blind Guardian, Thomen Stauch in a new project that would blend power metal with a high-concept science fiction story. The band's debut album Iron Savior introduced the story that would be told over the course of multiple albums, featuring a self-aware space vessel called the Iron Savior and its relationship to the mythical lost civilization of Atlantis.

Unification is the second studio album by the German power metal band Iron Savior. It continues the science fiction story that began on the first album Iron Savior. It is the only album to feature former Gamma Ray and Freedom Call drummer Dan Zimmermann.
