Groon

Earthbreaker Groon is a human monk, the dawn marshal of the Braving Grounds District in Vasselheim, and the highest religious leader of the church of Kord. His place of worship is the Trial Forge, a temple to Kord that also serves as a meditation and physical training center. As an NPC, Groon is played by Matthew Mercer.

Description
When Vox Machina first met Groon, he was an older human in his mid-to-late sixties with tough, reddish-tanned skin, a receding gray hairline, and a long, coarse, gray beard that extended to his beltline. He was short but stocky, and his stout body ripped with muscle from a lifetime of training in martial prowess and careful honing. He wore what appeared to be ceremonial robes of red and gold, simple wooden sandals, and a dark brown necklace of large, two-inch beads that adorned his neck and shoulders.

At first sight in the Crucible, the Earthbreaker appeared to have pupils, but in a later meeting, when he emerged from meditation, his eyes glowed with a pupilless white light. In this meditative state, the Groon referred to himself in the third person as "the Earthbreaker" and moved with effortless swiftness. He also demonstrated knowledge of events about which Groon was unlikely to know, such as Vox Machina's victory over Jurazel.

Encounters with Vox Machina
Groon witnessed Grog's victory in the Crucible against Kern, and he nodded and smiled his approval from the edge of the arena. Grog and the rest of his party decided to meet Groon, so they entered the Trial Forge to seek an audience with him. At first, Groon was in a meditative trance as the Earthbreaker, instructing Grog to ask his questions, but Grog didn't really have any questions so instead offered Vox Machina's service. Groon emerged from his trance, smiled, and accepted Grog's piety—then revealed that dark times were ahead. The Earthbreaker intimidated the party, especially Grog, who was fixated on the fact that Groon's eyes glowed.

Grog later returned to the Trial Forge after the Chroma Conclave attacked, and Groon put Grog through a trial intended to show the goliath that he should trust his friends rather than the dark blade, Craven Edge.
