So, how does it all work, this Chronopiracy?

Funny that you should ask that...

I have a picture that illustrates it all rather well.

Behold.
The chronolathe.

Note there are no hands involved!* The lathe makes the wand, finding the echo of the wand within, that corresponds with that original - located ...elsewhere.

So it's a sort of copying operation.
TPTB say that copying is piracy....
I say YARR!

hence, Chronopiracy!

*Trade secret. There may be many hands involved, There are.
