If not, er........bad idea, going back in time.
Either way, not the best idea. If your leaving Disco, sure. But for an RP story...should be more vague.
I only jumped about two years within my story I wont say Goodbye, but nothing changes, or has,a chanxe to, change the timeline.
The guy jumps back in time from when the Council and Sirius team up to destroy the GRN. As a member of the GRN, he jumps back in time without thinking in an attempt to escape the attack, but then realizes that he has entered a time period during which either the GRN or the Council can come out of the war victorious. While he is a member of the GRN (of the future, that is), he believes that in order to have been born, similar conditions to his own history must be matched. As his history involves the GRN getting defeated, he has every reason to fight the GRN to ensure that the Council comes out on top, and allows for himself to be born (though this logic is based on little more than the cheesy science fiction movies he watched for fun).
On his way to this time period though, he unknowingly kills his own grandparent which would, according to back to the future logic, wipe him out of existence (it doesn't, showing everyone reading in on his story that time isn't fixed, and that also, his time line never happens which means that anything is up for grabs - to eliminate any potential for metagaming.)
All in all, it allows for an alternative future GRN pilot to pretend to be a Council pilot from his past (something akin to an American being sucked back in time and being forced through certain circumstances to fight on the side of the British during the Revolutionary War).
