Sorry bout this, but I kinda yoinked Earth. My history allows for plenty of splinter factions though, so you can still easily play as humans. Just PM me if you want some more details and maybe we can work something out.
[/quote]Well, that puts damper on quite a few things.
I can still make this faction but I have to change almost everything about it.

I have two ideas which can work.
1.) They are descendants of colonists participating in a long range FTL jump experiment. They were thought to be lost but actually they were sent to a distant planet while also displaced in time. They built up their own unique civilization which barely resembles yours.

2.) Parallel development theory. Star Trek loved this excuse. Basically we are humans that developed on a different planet but very similar to Earth. Our language and culture has eerie level of similarities at times yet we are also quite different in other ways. If you watched the original Star Trek series you know what I am talking about.

Ironically I think 2.) violates our suspension of disbelief the least. We just need to come up with a name which makes my humans distinct from yours, at least when we refer to each other.
