He was Father Cornellos righthand man and a devout follower of his religion. Shortly after Ed and Als arrival in Lior Cornello explained to Cray that Ed was in fact a State Alchemist and was most likely in Lior for reconnaissance purposes. Consequently Cornello ordered Cray to eliminate the Elrics in the name of their god but he failed when a shot meant to take off Alphonses head only revealed his empty armor. During the siege of Lior Cray was devoured by Gluttony when he looked for Cornello and found the Homunculi instead. Crays skeleton can be seen in Gluttonys stomach near the end of chapter 50.
