Approximately what year is it? around 10,000? how long did it take to take over the milky way.

Also planning on playing a nation of post-biologicals, how high tech are we allowed to go....5000 years is a long time, Im thinking of making  my nation roughly Orions Arm levels but with less godlike AI and perhaps the addition of warp drive that can go mayby...100 times the speed of light?

Didnt meant to double post
