I agree with Vayelos3. The good guys hid the weapons (the good guys being the ancient kingdom) so they could stop the WG one day. Also there is no way that if the WG would be in possesion of the 3 ancient weapons they would just let them go.

I dont agree with your take on the formula mutagen for poseidon. I agree that the ancient kingdom was  technologicaly advanced but 800 years ago is still 800 years ago. They probably didnt even know what a imcroskope was back than.

Vazelos3 you know i have been thinking about raftel and i think that maybe Raftel is the only island on the grand line that doesnt have a magnetic field. A compas doesnt work on the grand line and if the log pod doesnt asweel what do you do ? Maybe there are dangerous sea currents that cant be navigated through and Roger was able to reach Raftel because he was able to hear the voice of the island that navigated him through.
