So, he's finally done. "The Guide". A NPC nobody knows, but everybody knows him at the same time. The guide does not appear in any dimension at all and remains in an unreachable dimension nobody even knows if it truly exists. The guide is entirely invulnerable and immortal untill every living being is dead. While he has no voice and you can't see any part of his body, you do know what he says to you. Quotes of the guide would be:
"While time shall reveal all, it reveals it to your enemies too. You must be ahead of time."
"You can depend on fate for the outcome of your story, but do you truly know what fate has in mind for you?"
"Honor and Pride are limitations to the mind. Release yourself from this and do truly everything you can."
"Your tales can only be told by you. You can change them, enhance them, but also end them."
