Ah, sorry about that. We may have given you the wrong idea by mistake. We aren't all writing one story together, but separate yet still relevant, independent stories; such as 13th's Obsidian Voyage series, or my One Dream series.

You can still add your personalized story to this wiki without jumping into anything big or complex. It's just that we have our stories operate within the same timeline as the One Piece canon; with one exception being Lvdoomien's Shells series, which takes place 100 or so years in the future. That's a rare, one time only exception though, as we're now more vigilant about these sorts of things.

The CP9 thing could work in my opinion. If your cabin boy came across them after the events of the Independent Report mini-series, then I don't see why he couldn't have received training from them, as long as Lucci and the others are willing to take on protégés.
