Cardinal Canyon is a location in the video game Sine Mora. Though picturesque, with cascading waterfalls, ample plant life, and towering rock formations, the canyon is also filled with dangerous, venomous beasts as ancient as the canyon itself. It is a mythical place, its narrow corridors long known to Enkies as a hunting grounds. Hunting beasts in the canyon is a time-honored rite of passage for Enkie men.

The canyon is a "sacred place" to Ronotra Koss, who once brought his young son there to hunt a Libelle.
