[Child of the 7th Age]

Perhaps, in a strange way, it is a bit like the making of the Ring itself. If you put so much of yourself into an object, whether for good or evil, that object becomes unique, a reflection of who you are. Some of your being actually passes into it. Should that object be destroyed, it can not simply be remade, even though you may have the raw materials to fashion a new item.

In our own world, I would thing of something like Michaelangelo's Sistine Chapel ceiling.
If something (God forbid!) were to happen to that work of art, no amount of our modern skill or knowledge could truly remake that ceiling and its pictures.

Now, we usually think of art or music or writing being a distinctive composition which can't easily be replaced. But why not a ship? If there are pieces of architecture, like Salisbury or Notre Dame Cathedral, which are so unique to be irreplacable, then why not a ship which is a piece of marine architecture?
