Kidou Senshi Gundam 00: Revealed Chronicle

The UN's Operation Fallen Angels leaves Celestial Being shattered, its Gundams damaged and its Meisters wounded. Hidden near Lagrange 3, the organization quietly begins rebuilding while engineers examine technologies that might allow its next generation of mobile suits to surpass what was lost.

Among those developments lies the path toward the Twin Drive System. Earlier machines, experimental equipment, and decisions surrounding the GN Drives reveal how the technology that will later define Setsuna's 00 Gundam began taking shape during Celestial Being's period of defeat and recovery.
