Stone is a rare material in Ardenweald. Yet, I've heard tales that those who were masked by the Drust have small stones upon them.
I'd like you to retrieve some of these stones for the Wild Hunt, so that we may better understand their link to our enemy.
Face the masked and collect the stones from their deceased forms and I'll compensate you for your efforts.
It's a gruesome task, but one that must be done.
