Ghast Priest of Orcus

As worshipers of Orcus, orcs have an affinity for demons and undeath.  Perhaps, because of their cannibalistic practices, Orcus has blessed orcs with the ability to ritualistically transform their infirmed and aged into ghouls and ghasts, the latter commonly occupying the role of priest of Orcus.  Because of this special relationship, orc ghouls and ghasts do not attack orcs as they would other creatures.
