The Gravetender is the boss of the Depths of the Painting. Accompanied by a greatwolf, the Gravetender is a warrior of unclear gender wielding their master's sword and shield and wearing a dark mask and chain armor. The sword is called Valorheart, and bears this description: "Weapon once wielded by the Champion of the Undead Match. A special paired set consisting of a broad sword and a lion shield. The champion fought on, without rest, until he lost his mind. In the end, only his page and a lone wolf stayed at his side."
When killed, the Gravetender drops the Champion's Bones, which bear this description: "Long ago, an Undead declared a fight. A fight to celebrate their Undeath, and to preserve what remained of their souls. So it was that the Undead Matches were born. The merit of an Undead is measured in deaths. Could there be a greater gift for such a creature, than a fight that has no end?"
