Velravn- Relic Contemptor Dreadnought.

Velraven, Lost in the vaults of the Raven Spire, said to be the last "living" Dark Fury member to be recovered from the Istvaan Massacre, rescued by Corvus himself and had his body crafted by the Primarch himself. After millennia of slumber, the discovery of the lost vault holding this ancient warrior, a dreadnought with the ability to take to battle field in the same manner of their gene father, a site to be behold on any battlefiend... and really why do we not have a dreadnought with a backpack?

Just Procedural Materials, working on the UV's hoping to make him a game asset later.
