Legio CXX

A destroyed legion made almost entirely of synths. the only few that weren't synths were the officers and some of the mech pilots. Known as tempered steel this legion was often abandoned and left to hold hostile planets by themselves with no reinforcements or reinforcements arriving to late. This lead to the hardening of the synths making many of them incredible soldiers. However this legion had one of the highest death rates due it being abandoned so much and by those not from the legion was nicknamed the bloodied steel.
