Revisiting The World's Core

"How much do I know and how far back, you ask?" 

The One-Eyed Venerable Shaman paused for a moment before he shook his head.

"This old man has read records of history dating back hundreds of thousand years ago, but the information is very incomplete—full of missing timeline in between. Still, if you ask me how much I know about history, Young Master Leonhardt could say that I know a lot. Or, I know nothing at all." 

"Because the truth of the matter is unless we have lived through those times, no one truly knows what actually happened. Anything can be written about history. It can be altered to mislead, subvert black and white, or changed entirely."

"This old man can tell you what this old man knows, but this old man can only guarantee that the past couple hundred years of history that this old has lived is true. Anything beyond that is an uncertainty."
