The Green Concern

Made of an alliance between orcs and goblinoids, out to defend themselves from genocide by the Elven fleets (so they say), but in practice it's a way for them to unite for larger raids on outlying wildspaces or loose planets/planetoids. They allow non-goblinoids/orcs in,as long as they prove strong and willing to obey the orders of their commanders, no matter how treacherous or violent the order might be.
