Dread

Dread is a warforged juggernaut who you've observed accompanying the Stargazers. He has two narrow eyes that glow red. His torso is barrel-shaped; in fact, it looks like it was formed from a large whiskey barrel that has reinforcing metal plates added on top of it to prevent it from buckling. The rest of Dread’s body is composed of overlapping steel plates, and his arms end in massive spiked gauntlets.

We know very little about Dread - neither his origin nor motivations.
