Elysia

Elysia is a verdant civilised world whose barren moons, gas clouds and asteroid belts have always been pirate cover, so the PDF learns boarding actions and grav-chute drops before anyone earns a Guard slot. The tithe therefore comes out as Elysian Drop Troops rather than line infantry: whole regiments falling from Valkyries with no Leman Russ column behind them. Jambonium parks the system in Segmentum Solar near Armageddon; a Lexicanum planet stub still files it in Ultima.
