Wait, so you're telling us, that dungeons are remnant heroic tales left behind in manifest memories. And many claim that the hero Kyle is a fraud, despite there being stories of him in said hero dungeon memoires? Can heroic memoires be artificially created? Wouldn't that mean that even if he was a fraud, that he had considerable power equal to said heroes to be able to recreate manifest magic powerful enough to be claimed as a dungeon?
Someone tried screwing with history, no doubt. But they don't seem to have done a very good job...
