the invaders. a evil warband that never stops moving, recruiting then enemies whole populations and forcing them to fight on alien planets with them. taking all your weapons and metal with them to use for ships and learning from you. been moving for 1000s of years, from leaders to leaders. a never ending mass of random species enslave now part of the culture and fighting the great fight! many ships from many aliens many weapons and peoples. *the Large alien grabs and bites your head off!* GLORY!
