Kevdak

Kevdak Strongjaw is Grog's uncle, a goliath, and the leader of the barbarian herd from which Grog originated. His barbarian primal path is Path of the Totem Warrior, and his totem animal is a bear. As an NPC, he is played by Matthew Mercer.

Background
Kevdak beat Grog nearly to death and exiled him from his herd after Grog refused to kill a helpless gnome, Wilhand Trickfoot. Wilhand's great-great-granddaughter, Pike Trickfoot, was able to save Grog from the brink of death with healing magic from a divine connection to Sarenrae.

Chapter 4
After the Chroma Conclave's attack on Westruun, Kevdak took advantage of the situation to grab power for his herd, which is now occupying the city. While dominating the Tal'Dorei citizenry in the region, the barbarians are themselves subservient to Umbracil, the ancient black dragon reigning over Westruun and surrounding areas.

Kevdak possesses the Titanstone Knuckles, one of several Vestiges of the Divergence that were thought to have been lost centuries ago. He also wielded a blood axe in a confrontation with Grog in.
