User blog comment:LeoHellstorm/The (possible) truth about purgatory knights/@comment-26024036-20150119232026

I think the Purgatory Knight were once Armor Knights. But when they went to the Darkness Realm or whatever they where mutanted and could not return. Now they fight for Dragon World from the Darkness Dragon World. It has shown so far that Darkness Dragon World has had very little contact with any of the other worlds. So maybe they just dont want to be bothered by other world, and have only come out of hidding now because of an imbalance of some sort. I think this is going to be a case of Darkness Dragon World not being being evil. But actually being good but being misunderstood. And the real evil is still out there somewhere.
