Xia Ya was attacked in 0093, a few years after 0079 and 10.

The important events in the middle are, 0083, Zgundam (0087) and ZZ gundam (0088).

After the 0079 war, the Duke collapsed, but there were still many remnants active, which the Federation did not pay attention to. After the war, Xia Ya and a remnant team went to the asteroid Aksis.

In 0083, the Federation commissioned Anaheim to develop the most advanced GP series airframe, in which the No.2 aircraft was able to launch the MK82 nuclear bomb by itself, which was later smashed during the federal military parade and the colonial satellite was also pushed into the earth. In the end, the remnant party was outnumbered.

After this incident, Xia Ya joined the Federation under an alias.

After the 0083 incident, the federal government set up an elite organization, Titans, to eliminate Jean's remnant party and give it a high degree of autonomy. However, the leaders of the Titans were ambitious. He gradually raised the power of the federal high-level, enlarged himself, and brutally ruled and suppressed the opposition.
