Firmament

Here's an excerpt from Firmament's Steam description:

Firmament is a new puzzle-adventure game by the legendary game studio behind the best-selling games Myst and Riven. Featuring deep storytelling and world-building, discover the story of this seemingly abandoned world as you explore and unlock the mysteries of 3 unique Realms… and beyond!

Featuring a unique steampunk aesthetic, Firmament invites you to explore the legendary deep world-building Cyan Worlds is known for. Firmament is a fantastic visual feast, with thrilling new sights to see around every corner. At the same time, the world of Firmament feels completely plausible; as though it were constructed with a bigger purpose in mind… A purpose you will be compelled to discover as you play.

You carry with you a device called an “Adjunct” as you explore. This Adjunct is your interface as you interact with the various devices throughout the Realms of Firmament. Employing the Adjunct to solve the puzzles you encounter will bring you ever closer to unlocking the secrets this place holds.

You are not entirely alone in Firmament. In addition to The Adjunct, you are joined by a mysterious apparition, who has a story of her own to share with you. As you explore you will be introduced to 3 Realms - each with secrets and mysteries to reveal. What purpose do the Realms serve? Can the spirit who accompanies you be trusted?

Are the realms of Firmament abandoned? What are these giant, mysterious machines scattered throughout the world? What is their purpose? What part do you play in this grand mystery? Explore, Discover, Solve, and Reveal the mystery for yourself by playing Firmament!
