Featherbent

The Strata serves as a homestead for a dichotomy of inhabitants: perches, who are passive, independent, and nomadic in nature, and hunters, who are built stronger, fiercer, with a higher population count, and a complex social network sorted rigidly by caste, the head of which make up the current ruling class.

Whether you're living by the light of mushrooms in the dark and damp Understory, within the bright, highly coveted spaces of the leafy Canopy, or the windy upper-class heights of the Emergent, the two classes live in harmony alongside one another, with all citizens celebrating their prosperity with a year-end tradition known as the Sweep.

When John Egbert carelessly treads the forbidden reaches of the Forest Floor, however, he finds that it shelters more than a few treacherous secrets about the place he was once proud to call home.
