I was thinking that we had several important groups during the series, besides the 7 deadly sins, there were the 10 commandments and the 4 archangels, what if something similar happens in 4KOTA? I know there are theories about Round Table Knights like Mordred being antagonists, but that's not what I'm talking about. I mean another group of important good guys besides 4KOTA, if the general consensus is correct and the 4 knights are Percival, Lancelot, Tristan and Gawain, there will still be other important characters that will be left out, maybe they form another group that too is relevant to the series, maybe some important group in Arthurian legends, I don't know, but it would still be missing Diane and King's son or daughter, and also Zeldris' son, if they have one, they could team up to form their own group with other characters, maybe in the future Donny Nasiens and Anne will also leave Percival's group, and maybe Edlin will join their group to complement them, just a thought.
