"Don't bother me, outlander. I don't need a mercenary, I need a miracle - someone who can tell me who slaughtered my men."
Quarry Foreman

Blood on Stone is a side quest in Horizon Zero Dawn.


When five night guards are mysteriously killed in the quarry at Cut-Cliffs, Aloy agrees to investigate the cause of the murders.

Talking to the Quarry Foreman, Aloy learns that one of the guards, Saravad, was a friend of his from their days as slave miners during the reign of Sun-King Jiran. When Aloy suggests that the guards were killed by machines, the Foreman explains that fences and gates protect the quarry from terrestrial machines, and that he doubts Glinthawks would attack in such a way.

When asked if he had noticed anything strange in previous days, the Foreman notes that they were using explosives to clear away some of the bedrock. Afterwards, Saravad had mentioned that he didn't remember a certain pile of rocks that had appeared out on the quarry; the Foreman had waved it off, stating that it was nothing unusual.

Investigating the quarry herself, Aloy approaches the mysteriously emerged mound. Shortly afterwards, a new machine, a Rockbreaker, emerges from the ground.

After defeating the Rockbreaker, Aloy returns to the Quarry Foreman who praises her bravery.
