This chapter gives some background on what happened during the MAC Crisis. I'll be refering to it a lot haha.
The M.A.C. Crisis had happened about seven years ago. The actual compound consisted of about five hangars, twelve missile silos, a large barracks for the troops, and the central building in the middle of it all. StarRex had used it as their basis of operations for quite some time. That is, until these boys showed up. After the wars, most people thought everything had been said and done, but StarRex decided that there shouldn't be peace. Not yet. The Murphey's owned the structure privately and allowed StarRex to occupy it for a certain amount of time. They had many wounded soldiers from a previous battle, but soon these men healed and once again became strong. James Murphey could not take on the whole corporation with only his wife and two children. Soon, the family was forced to abandon their home and move out to a remote location away from the colonies.
StarRex stayed after their departure and banded together with some other factions that were fed up with the peace. The crisis happened when James Murphey and his wife, Julia, went back to the compound to try and negotiate a year later. The commanding officer there at the time was Kirk Leland, a man who had been with StarRex for many years. He didn't sit with the Murphey's to hear their terms, but instead had them thrown into the basement of the main building. And that's when the Gundams showed up. They had been informed of renegade factions following the leadership of a fairly new organization determined to put a stop to the peace. StarRex would not leave however. Leland, instead, threatened the Gundam pilots with the Murphey's lives. They leave the base, then James and his wife live. Do not negotiate with the enemy. Destroy the base, that is your main objective and it must be completed. This is what they were to do, so Leland shot the Murpheys in cold blood. Then the Gundams destroyed what was left of the base, including Leland.
And this came to be known as the M.A.C. Crisis.
Their two children were sixteen-year-old Derek and twelve-year-old Jessie Murphey. Soon after the incident, Derek entered the war against Earth and fought with White Fang. After a tragic accident he was presumed dead and she went on to train at an organization called Diablo. They were a branch of StarRex, but after she proved to be quite an asset to their cause, they failed to inform her that. They knew she was one of James and Julia's children and realized that if she found out that they were a part of StarRex, she'd find a way to terminate them.
Now Jessie was nineteen and the pilots were twenty-two. All those years she spent at Diablo all she could think about was revenge for her parents and brother.
When they sent her to the pilot's base, she had no idea that they were the Gundam pilots that were practically responsible for her parent's deaths. And now she was their captive.
