Separatist Space, the story so far...
The RP takes place in "Separatist" space. Which is past protoss space. Some Terrans were exploring past protoss space (which is illegal might I add) and found even more intelligent lifeforms then they could imagine(all those custom races and such). With some funding from many governments and organizations, hundreds of thousands of colonists were being exported out from terran space and into distant space.
The colonists got tired of being bossed around by all of their shareholders and pretty much announced themselves separate from the Terrans in Terran space. Hence, the lands they colonized became, "Separatist" space and the colonists became "Separatists" because they supported the separation of separatist space and Terran space.
Many more events caused the separatist movement, but to sum it up in a few paragraphs, there ya go.
Separatist Space, Backstory
Entire colonies have been going missing, frigates carrying valuable cargo, gone. Terrans are still new to Separatist space and the Separatist Military is doing little to stop investigate.
This RP is extremely open, if you want to not engage in the main plot, that is totally fine, I would not recomend it but I will still allow it. Also keep in mind that at first you will have to pursue the main story, you will not start according to the main story. You will start out however you wish, wherever you wish.
