A game by Paul Veer and Roger Hicks for PC, originally released in 2011.
Celestial Mechanica takes place in a distant future where mankind’s endless warring and poor stewardship of the earth actually caused the planet to destabilize and break apart. Fortunately for humanity, a race of technologically advanced beings swept in at the last second and restored the planet. The celestial beings set up shop in a floating fortress called Mechanica and continued to watch over the earth to prevent its previous fate from recurring. 100 years have passed since that time, and no one has seen a Mechanian since they saved the earth. But of course, all of that is about to change.

At the start of the game, your character, a female Mechanian, is cast out of the floating fortress and falls to earth. Upon landing in a forest, she is greeted by a friendly Mechanian who has apparently been exiled to the planet’s surface as well. He suggests that they work together to find a way back into Mechanica and take down their angry and unjust king.
