Sandwhisper Valley is a mentioned-only location in Horizon Zero Dawn. Based on historical description, it appears to be located in the Rustwash region.


"In the winter of the seventh year of the reign of the Sun-King Hivas, did Darusiv, Hawk of the Lodge, stalk a herd of Tramplers from Sandwhisper Valley to the foothills of the Palereach."
