Time to make some drawings to define parts of the Khärn warrior armor. David did a great job specifying some of the designs that you can see in the first sketch. Our peaceful friend, as you can see, is ideally equipped for war, with metal parts that probably stole one time in a distant battlefield.
Kharn Warriors do not have the level of technology needed to shape the metal, they are only interested to tear enemies and eat their insides! So after every battle they wander among the corpses searching for interesting weapons and armor pieces.
Anyway, an average-sized Khärn warrior could only use a sword belonging to another race as a toothpick.
