Green Concern

The Green Concern is 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 Crystal Spheres 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.
