Prologue
Ancient history tells us that, Terra Venture was largely destroyed from it's second crash landing upon it's final resting place, Mirinoi. The distress calls from the downed space station would be answered by the KO35 Shogunate, who were still recovering from Dark Spectre's assault on their world; together with the Lost Galaxy rangers, and the GalactaBeasts, the wreckage of Terra Venture would be transformed into Mirinoi's planetary capital. It was decided by the Corbett Brothers, leaders of the new Mirinoi citizenry, to name the city after the Magna Defender; the faceless hero that died to save Terra Venture.
In time, the six Lost Galaxy rangers would separate, and help build five other cities on Mirinoi. 26 years would pass, as an unprecedented era of peace had fallen over the Sragosian Planetary Confederacy, until the Troobian Empire entered Sragosian space, declaring war on all planets in the S.P.C.. Suddenly Mirinoi, KO35, Onyx, Triforia, Aquitar, Sirius, and Alandria found themselves wrapped up in bloody space combat within hours of the Empire's arrival.
While the brunt of the war was felt on Earth, as this is where Emperor Gruumm had focused his forces; the planets of the SPC were suffering greatly. Alandria had been stripped of it's resources and obliterated by Gruum on his way to Earth.
Across the stars both galaxies grappled with the Troobians; and even though Gruumm and his main force failed on Earth, the fighting continued for another two years in and out of SPC territory. It was during these two years that Space Patrol Delta made a large push into Sragosian territory, fostering somewhat forced alliances with the members, and establishing a whole new headquarters for the Tau sector on Mirinoi, in Defender City.
118 years have passed since the fall of the Troobian Empire; in their time in the outer rim territories at the edge of known space, they have encountered and enslaved new races. These new subjects of empire surrendered a great deal of technology, resources, and soldiers to the Troobians; but with these gains came upheaval within their own ranks. One figure took center stage, a ruthless space pirate named Yeesildra. The might of this woman wasn't to be challenged, rumors swirled that perhaps she was a descendant of Astronema, or perhaps a monster from parts of the Universe that no one seemed to know too well. Under Yeesildra's iron fisted control, the Troobian Empire transformed into the Troobian Authority, and immediately laid waste to the Sragosian Alliance.
