How Does Uru Fit Into The Rest Of The Myst Series?

Short answer - it doesn't.

But you know there's more to it than that. Rand Miller, creator of Myst, is himself a character in Uru. In the Uru universe, Mr. Miller created the Myst series based upon information that became available to him through the restoration and the DRC. So, in Uru, the Myst games and books are speculative and should be considered works of fiction. How much of them fits into the world of Uru is a matter of conjecture.
