User blog:Fintin/What is One Piece?

So, there's been many news and talk about the Straw Hats going to Fishman Island, the strength, their bounties, etc. Whenever something new comes up, it's practically eaten up by OP fans, and it's talked about. But, I've been thinking about the old foreshadowings, events, and all the like. One of these was about the One Piece. Is it alive? Or inanimate? Is it a physical treasure? Or a spiritual treasure? Is it treasure? Or something to treasure? Is it worth money? Or worth experiencing? All these questions come up in my mind when I think of what One Piece is. Basically, what I'm wondering is, what are the Straw Hats going after in the first place? I'm really interested in what you guys may predict, so feel free to make a guess!
