The War-Chief's Trail is the eighth main quest in Horizon Zero Dawn. After talking with Varl at the gates of Mother's Watch, Aloy learns of the failed war party led by War-Chief Sona that has gone missing. As the son of Sona, Varl pleads with Aloy to find her.
Aloy makes her way to the battlefield where the Nora war party was last spotted. The field is littered with the corpses of machines and Nora Braves. A stampede of corrupted machines ran down the slope and clashed with them. The war party was able to kill a Corruptor in the ensuing battle. During her search, Aloy comes across Dran, a wounded Nora Brave. He tells her that the dead and wounded have been cleared away. War Chief Sona sent him back to report on the situation. The war party was on the trail of the killers, but corrupted machines threw them off their trail. Dran tells her that he last saw Sona at the metal tower southeast of the runs of Devil's Thirst.
Aloy makes her way to the rise within the Devil's Thirst and finds a recently-used camp. The campsite is filled with spent medical supplies as well as a bow and arrowheads left behind. She uses her Focus to discover a blood trail that leads up onto a ridge overlooking the Devil's Thirst. She reaches the top of the ridge and finds an inactive Corrupted Sawtooth. After pulling an arrow from the machine, another Sawtooth stalks up to her. Before she can react, an arrow strikes the Sawtooth and forces it off a cliff. The arrow came from Sona and the remnants of her war party.
Sona tells Aloy that she has tracked the killers to a nearby camp. Aloy spots barrels of Blaze throughout the camp and suggests that they ignite them to turn the tide. Aloy, Sona and the Nora party dispatch the camp. Varl appears and tells her that he wishes to rain vengeance on the killers. By examining a Datapoint, Aloy discovers that the remaining killers are camped inside a Ring of Metal. Sona tells Aloy that it's located in the Devil's Grief.
