Linking books are the special craft of the D'Ni people. "The Art", as it is called, involves using special paper and ink to write books. The details written in the books and their structure determine which of the infinite worlds it will link to.

One must remember that when these books are written, the ages described are not being created, but only a gateway is being created.

Some of the more famous worlds, linked to by the family members of Atrus, would be Myst, Riven, the Stoneship Age, the Mechanical Age, the Channelwood Age, and the Selenitic Age.
