Selenitic is an Age written by Atrus.


The Age was an uninhabited island. When Atrus linked to the Age, he found a lush and green landscape and enjoyed the silence, but a mysterious hot wind gave him a strange feeling that he was not welcome. He slept on a green hill, but he woke up by terrible shaking in the ground and explosions as fiery meteors fell from the sky.[1]

Atrus returned 3 months later (bringing a new Linking Book as the one left behind would have been destroyed) and found a brown and barren land. Despite this, he enjoyed the various sounds that constantly flew through the air and explored to find their origins.[1]

One night Atrus awoke by a hissing sound and heat and soon after he witnessed a roaring, wide chasm opening nearby. He considered harnessing its energy and, despite the heat, he reached a newly-created cave, an entrance to a vast underground cave system deep into the crust. He left and then returned with tools for his plans to explore the underground and, thanks to the abundance of raw materials, he didn't need more.[1]

In the following year, Atrus begun working, he built bridges, a rocket ship, an Antenna detecting sounds, rails spanning inside the cave mazes, a Mazerunner designed according to D'ni technology (and help from Sirrus),[2] and others. On that Age Atrus employed one of his most prized inventions. During that time Sirrus and Achenar were spending time alone in Channelwood. He copied many of his construction notes in another journal. After about 18 months being there, the Age had stabilized. While leaving, Atrus considered visiting another Age which would provide answers to Selenitic's mysteries.[1]

Atrus returned to Selenitic in order to bring over some of the machinery left there, and to use them for his constructions in Rime.[3]

As an uninhabited Age, Sirrus and Achenar found no civilization to exploit there.

The Linking Book to Selenitic was powered by machinery, although its details were obscure.[4]

While writing Releeshahn, Atrus revisited the Age, and felt the same disturbing feeling as always.[5]


Selenitic is an uninhabited island on a shallow planetary crust. At first it formed a beautiful landscape with a grassy hill above green fields, a few scattered forests and a large lake. In the north there was a chasm whence an uncomfortable hot breeze came to the south. The sky had a few white clouds and the sunset was spectacular with oranges and reds. During night reds still were seen beyond the horizon that blended with the black of the sky.[1]

After the cataclysm, it became a barren land, with scattered gigantic craters. The meteors pierced the shallow crust and set off a period of volcanic activity. The cataclysm did not affect the grassy hill, which remained as a grove with a stream, an oasis among the barren desert. The lake was dried up, but one of the meteors created a large gulf with a rock jutting out of the center of the lake. The northern hot wind turned into a pleasant breeze. Despite lacking features, the environment was rich in sounds: streams, whistling winds, fiery chasms, the sound of wind whistling through peculiar crystalline formations. Later, near the oasis, fires came from the ground and a tumult opened a fiery chasm, revealing a vast system of underground caves. The raw materials were abundant, mostly iron and titanium.[1]

From the start Atrus believed that the energy of the Age was unfocused, as if it was in war with itself.[5] He observed that the Age hid many mysteries, one of them that a large portion of the writings in his journal about the Age had vanished, but, despite his best efforts to discover why, Atrus could find no explanation and simply accepted it.[1]

Points of Interest[]

  • An Oasis, on the SE end of the island, the only part unaffected by the cataclysm and thus has a few trees and a small pool, there's also a bench and a hanging microphone that captures the natural sounds.
  • A Chasm with flowing lava, crossed over by a bridge. Is boiling sounds are captured b y a microphone that hangs above.
  • A building which opens with a sound-based combination. It leads to an Underground Maze.
  • A Spaceship Pad, with a Spaceship like one on Myst. The spaceship is identical to its counterpart, but inoperable. Its door is open, but once someone exits, it closes automatically with no discernible way to open it again.
  • A Ruined Clock Tower, obviously built by Atrus. It appears rather as a gigantic grandfather clock with a pendulum than the functioning one on Myst Island. A microphone captures its mechanical sounds.
  • The Stone Forest, with crystalline formations protruding from the water. Atrus built a bridge that leads among them; the wind that moves through them produces a whistling noise captured by a hanging microphone.
  • A Wind Tunnel, which goes underground, where bats have retreated from the oppressive heat. A microphone captures the whistling wind. It leads to the central islet.
  • The Main Antenna Controls built on the islet that stands in the center of the crater lake. The antenna receives sounds from the microphones around the island .

Early Concepts[]

In an early concept map of the Age, the Age would be visited by the same Spaceship that exists on Myst. Once the player arrives, the Spaceship is not powered is therefore dead (in the final game, the Selenitic Spaceship is just an inoperative replica of Myst Island's).

There would be no ruined clock, but rather "Selenite Hot Springs", being a source of a bubbling cauldron sound. The "Selenite Oasis" as well as the "Selenite Hot Springs" would contain clues for the identities of the brothers.


The abandoned maze concept. A render of the maze has been published in the Myst Screen Saver.

The Linking Book on this Age was originally intended to be housed in a complex underground maze of overlapping catwalks and ladders suspended over an enormous chasm. Like the maze in the final game, this too would make use of sounds to direct the player to the correct direction. In the early conception, the maze would end to the Myst Room with the missing pages and the warp area to the Myst library.

However due to the vastness and complexity of the maze, the rendering time would be prohibitive due to the technology of the time, and so it was replaced with the Mazerunner.[6] The Mazerunner sequence consisted of prerendered videos which however could be replayed, giving the illusion of a large area.

Notes & Trivia[]

Overview of the island in wireframe stage.

  • The Age was designed by Chuck Carter.[7]
  • Richard A. Watson has commented on the name of the Age as being related to the moon (Selene being the Greek name of the Moon, and its goddess). It is possible, but not confirmed, that it involves selenite, a certain mineral which may be present in the Age and might be what the crystals are composed of. The name could also simply be a reference to the barren rockiness of the place, resembling a "moonscape".
  • Selenitic is the only Age in Myst (not including Myst Island itself) that was naturally uninhabited at the time Atrus linked to it. As such, Selenitic is the only Age where the brothers have no respective living spaces, but the book pages are still found.
  • Selenitic is also the only Age in Myst that has no Linking Book; instead, a spherical screen is activated by the organ puzzle in the rocket ship, which functions as a Linking Panel. Watson has explained that this is how they rendered the information that the book was powered by some sort of machinery.[4] In Myst VR however, the organ puzzle causes a round panel to revolve, revealing the Selenitic Linking Book attached there, which can be opened normally.
  • The name "Selenitic" is never heard or written in the original game, the package or the manual. It can be seen only in the CD game files, or afterwards from the hint books and the Myst Soundtrack. In realMyst, one of Atrus's journals has the words "THE SELENITIC AGE OF MYST" on its spine (which could be the same words in the original game, but are not really legible). The phrase "Selenitic Age" does appear as the name of a data file on the CD of the original Mac version.
