I don't see why the wg needs to find it. They already know about the blank period or whatever. They have all the treasure they need. If anything it being hidden at Rachel helps them . they only need to stop others from finding out about everything if anything. Roger did them a favor leaving it there and now all the wg really needs to do is just prevent people from getting thereWhen have we ever seen a hint towards the WG wanting to find it? Considering that we know a war will engulf the world when it’s found, a statement that Sengoku’s reaction to and the speaker of gives credibility to, why would the WG want it to be found period?
