History
From Home Is Where I Want To Be
A vague timeline at least, a more intricate examination of events would be better. Some of this can get hashed out now, even before I figure out if these characters are human, post-human, or non-human.
Interstellar travel
- Reliable interstellar travel is only 50-80 years old
- Several worlds colonized and in better political and resource shape than home (US history analogue)
- NO alien sentient beings to displace. Just flora and fauna. Terraforming?
- Terraforming - if you can make interstellar ships, you can terraform.
