Master armorer was a title within the Je'daii Order as well as the Imperial Knights. It was held by a Master who, among other things, was responsible for crafting specialized, life preserving armors for Imperial Knights severely injured. By the time of the Second Imperial Civil War, the master armorer was Hogrum Chalk, a former Imperial Knight who had suffered a severe accident that forced him into a life support suit of his own and also a secret Sith Imperial spy.
