About This Game

The Heights are a gorgeous utopia. The Depths, a filthy industrial wasteland. Our heroine, raised in the Heights, has nothing but contempt for those below. Now an observation mission requires her to descend into that world, and the gears of fate have begun to turn.

This story takes place two years after the "Grand Ending" from the original Steam Prison. While riding the "buggy" invented by the engineer (and information broker) Ulrik, our party arrives in the new land of Cainabel, where they meet a pair of kings. The story unfolds from there.

The stories of Ulrik, Adage, and Fin take place alongside the younger king Jevite in this strange land. Meanwhile Eltcreed, Ines, and Yune clear the way to Cainabel's future with the elder king Jereme. You can enjoy this episode and its endings from two points of view, depending on which party member the heroine travels with.

This release also includes an additional story titled A New Theory.

In A New Theory, our heroine must confront the injustice of her world. She makes contact with the HOUNDS in order to clear her name, and decides to forge a new path for herself...

Cainabel Story plot summary

Two years have passed since the unification of the Depths and the Heights, and the creation of a new government.

With those in the Heights now free to choose their own romantic partners, our heroine spends her days ducking meetings with potential suitors arranged by her mother.
