Kevdak

Kevdak was Grog's uncle, a goliath, and the leader of the Herd of Storms, the roving barbarian herd from which Grog originated. His barbarian primal path was Path of the Totem Warrior, and his totem animal was a bear. He also has at least two combat maneuvers, (disarming attack and pushing attack), gained from the fighter class or martial adept feat. As an NPC, he was played by Matthew Mercer.

Background
Kevdak beat Grog nearly to death and exiled him from the Herd of Storms 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 possessed 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.
