Titanstone Knuckles

The Titanstone Knuckles are a set of powerful gauntlets, and one of the Vestiges of the Divergence.

History
According to Kamaljiori, the Titanstone Knuckles were taken from the brutalized corpse of their proud owner and worn by a terrible half-giant turned tyrant in Westruun. According to Grog Strongjaw, his uncle Kevdak possessed the Titanstone Knuckles as one of his two prized weapons, but it is unknown if he understood their true origin or power. After Vox Machina successfully dispatched Kevdak, the large gauntlets were passed to Grog.

The Titanstone Knuckles became exalted after Grog just barely defeated Earthbreaker Groon within the Trial Forge, the temple of Kord in Vasselheim. Two beams of light, similar to lightning strikes, came down from the ceiling of the temple, hitting the gauntlets and causing them to glow.

Behind the scenes
In early 2013, "about 10 years ago", Travis was sitting on Riverside near Don Cucos expandin on Grog's backstory and strongly felt that Grog's uncle, Kevdak, needs knuckles, giving them an expressive name of Titanstone Knuckles. Travis sent this idea to Matt, who already had a concept of Vestiges of Divergence in mind and thought "that would be a fun one to make into a Vestige".
