There have been severalMe ' Rak Incursion Me ' Rak were considered invincible as they annihilated countless civilizations . That was until they ran into a Dar Mataan hive fleet , the Me ' Rak were defeated for the first time . This was the first glimmer of hope as many had given up completely . The Dar Mataan couldn ' t defeat the Me ' Rak on their own and got support from their allies the Shani Na Rada . However , they were still getting slaughtered on the ground by Me ' Rak infantry . The Iskarn were approached and soon proved capable of fighting Me ' Rak infantry on a equal level . The Trinity was born , they could now start fighting the Me ' Rak instead of always being on the defensive . Trillions upon trillions of lives were saved because of this . The Reach Massacre , the Reach was the lower part of a spiral arm in the Twin Blade Galaxy . The Me ' Rak broke through the Trinity defenses and started glassing close to a thousand inhabited worlds . This event saw the near total destruction of the Iskarn Herkur Segment and the Dar Mataan Emerald Hive . The Trinity forces were spread so thin that eventually the entire top half of the Twin Blade Galaxy was at the mercy of the Me ' Rak . The Blade Offensive , the Trinity ' s answer to the Reach Massacre . The Iskarn ' s Sagis Segment had previously been held in reserve as the Herkur Segment was on the front lines . The Iskarn Collective had used the Sagis Segment as a dumping ground for defective Iskarn . The Sagis Segment proved its worth a thousand times over by completely purging the Me ' Rak in the Twin Blade Galaxy within 15 years . They had failed prototypes unusual abilities , obsolete designs combat veterans and those who outgrew their programming emotions andor a ability to think outside the box . They also managed to gather the remnants of the Herkur Segment and the Emerald hive . The Hidden The Hidden knew about the war between the Trinity and the Me ' Rak . They were pretty paranoid and started slowly converting other species into their servants the Uplifted . This was to beef up their industry and military to eventually fight both . The Hidden had started with secretly converting humanity . The unthinkable happened when a Iskarn stealth ship accidentally ended up in the Milky Way . It was the beginning of the end for the Hidden when the crew finally managed to contact Trinity . The Andromeda War , actually a war in the local galactic group 50 galaxies . The Trinity engaged the Hidden when their army was only at 4 ~ 5 % of the desired strength . The war halted the secret conversion of countless species and created the Andromeda Union as a faction for the Uplifted after rebelling against their masters . The Starborn The Starborn terraformed worlds at incredible speeds into horrific alien jungles . They gathered the humanoid populations in domed cities where they ' d effectively become their cattle . The Starborn absorbed the brains of people over 40 years old . A major turning point was when the Andromeda Union was being attacked by the Starborn , they started pushing back and freed thousands of planets . The Guardian alliance , many children grew up in the Trinity Protectorates in the wake of the Me ' Rak Incursion . Many would join a peace keeping organization known as the Guardians to deal hostile stellar powers , pirates and slavers while the Trinity was fighting the Me ' Rak . A large number of young humanoid Guardians would allow themselves to be captured by the Starborn so they could sabotage the people farms from the inside . This gave the Andromeda Union a major advantage as they themselves were too easily detected and killed . The Trinity offensive , the Trinity was capable of sending troops of their own after the Me ' Rak were sufficiently driven back in other galaxies . They also gifted the Andromeda Union a new piece of technology , a Breach Sealer . They could now manufacture devices that could close the dimensional breaches the Starborn had been using to travel to our dimension .
