Another query about Dark Zones is that, how is it that Dark Zones can simply exist? What kind of power is required to actually explore a Dark Zone without becoming Corrupted or simply dying, or just forgetting everything if one were to survive? I can totally understand the mystique behind it, but if Dark Zones are simply dangerous, unexplored areas of the world, then wouldn't that mean all else was a Dark Zone once upon a time as well? (You know, aside from when the world was presumably on fire due to the whole double Sun situation (stupid Nairyf).)

Surely someone or something should be capable of shedding light on them.
