[@Klomster] Sounds pretty good, you'd actually fill in the last slot for the Garden Nations. You're also welcome to add in two more species alongside the Schäferkin, if you wish to add any more that is.

[@Ozerath] Option 2 definitely sounds good. Would they be human at first or would you be more open to other options? My nation will be federation between it's three native populations(and a significant immigrant population from other worlds). My main race for the federation would be the Ishkaan, aka Not!Turians :P
