You can immediately give away the colony.
When you start as Mayasuran in Nex, you start with a comission, and as "governor" of the colony.
You can talk with the colony administrator on the comms screen, and "give" back the colony.
Not sure why you would do that though, they risk getting wiped out early without you having a chance to learn all blueprints and whatnot.
EDIT: repleid the guy question and forgot to post what I wanted to post
So I wanted to know if the mod now will use the new features to let you actually play out the mod tagline, for example some conversations with characters about terraforming, maybe interaction with the other terraforming mods and giving you rewards if you fix the planet, maybe a supership if you wipe out luddic path, etc...
