The earliest "Knights" were the elite combat forces of various nations, extremely rare and difficult to cultivate. The real reason for this circumstance was the cumbersome and inefficiency of the Magic Guided Conductors of that time.
Since there was no Magic Guided Reactor integrating the Core Crystals, each Magic Guided Conductor of that time had to have its own specialized Core Crystal. The Core Crystal, along with the various components assisting its operation, was massive and complex, requiring the "Knights" who used them in combat to have a physical condition far beyond that of ordinary people.
In that era, the design philosophy of Magic Guided Conductors was to value size as beauty, with its epitome being the precursor to Dragon Knights—the Giant Construct.
