Here is one of the other models in MkIV armor, a Betrayal at Calth Chaplain. Originally, I was planning on giving him the usual bone white armor, and a black cape, but then I remembered the Chaplain character from the quick read "Distant Echoes of Old Night", and went to reread that. Yep, black armor! His crozius and collar are a light brighter gold than would be expected for the Death Guard,
