You're trained in your chitinous plates. You can wear a flight suit over your exoskeleton, but you can't wear other armor.

The peoples of the Pact Worlds (and other worlds in the galaxy) are many, and they have a long history of intermingling or dabbling with forces capable of altering the very fabric of a mortal body or soul. The children born to such parents might have traits from each of their parents or physiological manifestations of the forces their ancestors were influenced by, manifesting as a specific heritage.
