Chaplain Arrioph
Arrioph is the chaplain of the 8th company. He's one of Castor's own, raised from the cradle to marine-hood so to speak, and promoted by the Apostle's Will and Word. Arrioph was bought as a slave from the fighting pits of Merioop, a Daemon World largely dedicated to Khorne, because Castor saw great potential in the boy. He has all the qualities Castor values in his marines - loyalty, zeal, martial prowess, and the ability to use tactics and discretion when the situation warrants it.
