Order of Ghosthunters

The greatest enemies recognised by the original Order of the Forbidden were the servants of the Colossi and of the Undying King. In time, as individual Blood Hunters specialised in opposing and co-opting the tools of one or the other, the Order divided into the Order of the Unhallowed and the Order of Ghosthunters.
The Ghosthunters devote themselves to battling the undead, and peering into the world of the dead results in a slow transformation of their eyes. At first, they simply gain a milky film, but as a Hunter progresses they almost seem to sink into shadowed hollows as a darkness spreads in rays across the skin around their eyes.
