The Great war Paradox

The Great Wat of Aevilon caused a rip in the very fabrics of the universe that altered reality in a way that had never happened previous the the event. The entire history of Aevilon was completely changed with somethings that had previously happened Never existing, the galaxies seemed to be more isolated from each other as they had no interaction between each other until the present day. Brothers of old now didn't even know each other and beings of power managed to usurp power of certain galaxies.
== Explanation ==
There is only two possibilities of events, those that happened and those that never happened. Before the Great War many things happened, the Great War paradox changed them as it ripped everything apart and everything was different. Supposedly the universe changed size, some beings and entities completely disappeared out of any sort of existence. What I explain is the past of how it happened after the events of the Great War.
