[@ClocktowerEchos] Well, the primary driving force is something i'd like for players to find out in game. :P
I'm gonna try and have the Schäferkin kinda alien compared to humans.

For example, no innate need for religion.
Seeing that the questions "Where do we come from, and why?" are already answered, and there isn't much complex philosophy behind it.

[@Sigma] It's natural for the others to feel sorry for the Tak'a'dis. They were actually kinda chill, apart from making their slave race. Making trade and beginning to work on interplanetary relations. (If they had good relations, their friends would just help curbstomp the Schäferkin uprising, and that story is already a bit implausible :P)
I guess they probably was a bit vain, since they didn't take help from the other nations when the uprising turned sour.
So a bit vain, a bit superior in their attitude. Definitively someone other species could work with.

[@JuliusCaesar] I'd like to have a small amount of trade and a VERY uneasy trade agreement with Vesia.
After all, you are scaly folk, and you can't really trust them. Something the Vesians probably have realized looking at the Schäferkins history. :)
