Time traveling characters

[Schatten Research Facility]

I'd like to make a time traveling member of the GRN who, during the last stages of the joint Council and Sirian campaign against the last vestiges of the GRN several hundred years into the future, managed to escape from a Council attack on the research facility on which he was working.

During his daring escape, he manages to grab a well preserved museum relic (a long obsolete model of a GRN (a slightly less obsolete version of the council) gunboat, which the local commandant had kept in restored condition as a "classic muscle ship" to catch the attention of the ladies, and finds himself in the current time period Gallia.

Due to his gratuitous amounts of exposure to the cheap and cheesy science fiction holovids of his day, the time traveler believes that to cause any deviation from his "established" time line would be to spell doom for himself in a classic example of abortion via never happening. As such, the time traveler must, despite his horrendous knowledge of history, attempt to assure that the Council and the Sirians win the war so that things remain more or less the same, with the Council and Sirius ultimately triumphing against the GRN so that he may live (or so he believes).

Unfortunately, the traveler accidentally kills his own grand uncle who, in a strange turn of events, was destined to also be his grandfather (apparently Gallia has its own version of the deep south). Time irrevocably altered, the traveler unknowingly emerges as a product of a time line that never happens, but with every reason to ensure that the GRN loses the war.

Thoughts?
