In truth, Dyon planned for the minimum requirement to be that of a Comet Lord in the future. But, for now, he could only loosen the standard. Even the best of the former soul slaves were still middling around in the Master Realm, but, in just a few more years, even a few short months for the likes of Masada, they would slowly begin to meet Dyon's needs.
Eventually, Dyon envisioned an Array Alchemy Faction that stood above the guilds. Not just any Comet Lord could enter, only the best could enter. Only by attaching such pride and prestige to certain things could Dyon slowly brew a culture. But, he knew that he had to be careful, or else with that pride would come a sense of entitlement and elitism. It was a delicate balance.
