The Greatrun River is an unmarked location in Horizon Zero Dawn.  It is a river running through the center of the Sundom, in the Greatrun River Canyon[1], primarily within the Gatelands region. The Carja settlement of Lone Light rests on a cliff overlooking the river, near a bridge along the Way of Broken Stones. It forms the border between the Gatelands and The Jewel.
