The Second Stage Turbine Blade is the first studio album released by rock band Coheed and Cambria. It was originally released on February 5, 2002 through Equal Vision Records. It is the second part of a five-part pentalogy, telling the story of The Amory Wars. It was re-released on September 20, 2005 and included three previously unreleased bonus tracks.
The album introduces the husband and wife characters Coheed and Cambria, the characters from whence the band's name originates.
Husband and wife Coheed and Cambria are used as the centerpiece to enable Supreme Tri-Mage Wilhelm Ryan's attempt at destroying his archrival Mage, Mariah Antillarea. Due to a memory swiping years ago, the couple are led to believe that their former lives have now come back to haunt them. They’re told by General Mayo Deftinwolf (Ryan's Right hand) that they were long ago implanted with a great threat to Heaven’s Fence, The Monstar Virus. A virus with the ability to turn its host (Coheed) into a being powerful enough to drain the Keywork's energy sources to spark Armageddon, while their dear old counterpart, Inferno was given the only means to unlock it. Through more lies, they are led to believe their children have genetically acquired a mutated form of the virus, the Sinstar. This new strain only requires its host to mature to a certain age, and has no antidote unlike the Monstar. Their children cannot be saved and time will not side with them. Coheed and Cambria are faced with an unimaginable dilemma: to murder their own children or face Armageddon.
