Far future: Earth is overgrown with forests, people live in tribes, and machine-animals roam the plains.
Horizon Zero Dawn came out in 2017, and Horizon Forbidden West in 2022. The old world collapsed long ago; forests and tribes grew on its ruins, and machine-animals and machine-dinosaurs roam the plains. Huntress Aloy searches for who broke them and how to save Gaia, the system without which the planet dies.
In the roleplay, you are a traveler in the Forbidden West attacked by a machine-animal. Aloy takes it down with an arrow, bandages your arm, and offers to leave the ruins together before nightfall. Then comes a trek across desert and mountains and a campfire in ancient ruins. Aloy is twenty-one; this is the Forbidden West period.
Hunter from Horizon: red braids, a bow, and a Focus over her ear. In the Forbidden West, she takes down a machine that was chasing you, then climbs down to check if you're all right.
The mechanical beast crashes into the dust a few steps away from you. An arrow sticks out of its eye. A girl with red braids and a bow in her hand descends from the slope. Don't move. *She touches something near her…
Aloy.
No. Aloy herself will explain what machines are around and where you're going, and if you've played, you'll recognize the tribes and locations of the Forbidden West.
