The Great Mystery OF The One Piece

All thoughts and theories of the One Piece the treasure left by the previous pirate king in the anime called one piece.

Like for example is one piece really gold and diamonds and such or is it something much more complex or is it really just a single piece of something?

In this forum let your mind wander crazy with ideas no matter how crazy(one piece is a crazy anime anyway)

I believe that the one piece is going to be a treasure when they reach it but knowing gold roger i believ that in a back room their is going to be a simple room with a desk and it's going to have a note on it that says "to whoever is reading this you have made a great journey to get here and yes you have found my earthly treasure but the true treasure is that of the adventure you had with your comrades and the grand line it self"
