So I have a few questions for an RPG backstory I'm writing.

I know the universe is expanding faster and faster, in fact faster than light once you go out far enough, but where is the "breaking point" between what's reachable and what's not? How far could a ship sent out a few thousand years from now reach, travelling close to the speed of light?

More importantly, how far could the progenitor race have made it a billion and a half years ago? I already have them settling in the Local Group of galaxies, but could they have made it farther?

In the setting both wormholes and alcubierre warp drives are a thing to technically go faster than light, but they can only be used to reach point that have already been settled by STL ships.

I mean if a colony ship from Earth was sent out a thousand years from now, travelling at almost the speed of light, what's the farthest it could possibly reach before spacetime itself is expanding faster than it can travel?
