The Spurflints Keeper is a minor character in Horizon Zero Dawn. As Groundskeeper of the Spurflints Hunting Grounds, he oversees the Stealth Trials.
History
Before becoming Groundskeeper, the Spurflints Keeper was no different than many of his fellow hunters, approaching hunts with haste and impatience in an attempt to gain status among the ranks of the Hunters Lodge. It wasn't until he came to the Spurflints, where he was forced to utilize patience and stealth, that he realized that this initial approach took away much of the enjoyment of the hunt.
The Spurflints Keeper has since mastered the art of stealth and become Groundskeeper.
