I engaged the Vonnegut ’s autopilot, then activated my Ring of Teleportation by speaking the command word, "Brundell." When the ring began to glow, I said the name of the planet where I wished to teleport. A world map of Frobozz appeared on my display. It was a large world, and like the planet Middletown, its surface was covered with hundreds of identical copies of the same simulation—in this case, re-creations of the Zork playing field. There were 512 copies of it, to be exact, which meant there were 512 white houses, spaced out evenly across the planet’s surface. I should be able to obtain the Jade Key at any one of them, so I selected one of the copies at random on the map. My ring emitted a blinding flash of light, and a split second later my avatar was there, standing on the surface of Frobozz.
