Just a question: IS it possible to have an ancient species that went extinct, but has some population samples still preserved in various, unknown sites? Obviously, they would be severely limited in numbers, territory and understanding of current affairs, but it's an idea I'd really like to explore. Just throwing that out there :P

Yes that seems totally ok :)

:@Monkey pants: The orion arm doesn't meet the crux-scutum arm as the orion arm isn't an arm at all it's a spur. The Orion Arm is located between the Carina–Sagittarius Arm (toward the Galactic Center) and the Perseus Arm (toward the outside Universe) and so the carina sagittarius arm is always between it and the crux-scutum.

I'm assuming the tachyon weapon works by exciting tachyons in a chamber that then impart impulses on the matter dumped in?
