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.

Taken from the liner notes in the booklet of the CD release.

In the year 2110, earth is controlled by the Iron Savior. The gigantic machine - built in Atlantis to defend the lost continent against its enemies, the so-called Alliance - still is mistaken. The computer-unit analysis identifies man as the destroyer of Atlantis. So it continues to carry out its prime directive: Protect Atlantis and conquer the Alliance.

On earth only a few people managed to hide from the bloodhounds of the Savior in the former Earth-Defense-Headquarters (E.D.H.) underneath the everlasting ice of Greenland. The machine, from the very first moment of its arrival, was transmitting signals directly to the Atlantic Ocean, North Africa, South America, and the Easter Islands. This behavior led some people to the "theory of Atlantis". And in fact after major research for anything related to the old myth, some artifacts were found on the Azores and on the Easter Islands. The dig on the Easter Islands uncovered something like the entrance to an ancient structure of unknown purpose. Shielded and protected by force fields of unknown sources, the station couldn't be entered by anybody yet. But all of a sudden another transmission - similar to the Savior's transmission but yet different - was detected. Sensors indicated that the source must be located right in the heart of the ancient structure.

The attempts to enter the station made the last Atlantian on earth awake from his 300,000 year long stasis sleep. Now the "Sleeper" is the last member alive of the Atlantian Iron Savior Defense program. But when he transmitted the secret codes to direct the controls of the Savior to his station, something unexpected happened. The computer unit refused to obey his command. It almost appeared to him, as if the unit is conscious - with a will of its own, just like an organic life form.

The awakening of the sleeper and the contact with the last Atlantian on earth brought a lot of clarity and turned the "theory of Atlantis" into a hard fact. On the other hand, the situation did not change at all since the machine seems to disobey the orders of its creators. The only chance to fee mankind from the Savior is now awake to bio unit. But even this seems doubtful if the robot in deed developed a consciousness and now acts like a being with emotions and the hunger for power. It is very much likely that the computer will also disobey the orders of the bio unit. So the Savior needs to be defeated or destroyed, which at this time seems to be impossible.
