Moses was a dark skinned man with close-cropped hair and a mustache and goatee. He wore a knitted polo neck sweater underneath the warm Eskimo clothing favored by the residents of the Bradley Shelter.
Like the rest of the Merlin team, Moses was introduced when Arthur Farrell showed it to Vilma Fachiri in ES 126. When Merlin spontaneously rebooted itself following Haruka's death, the voice box team connected the artificial voice generator. This enabled Merlin to deliver its prophecy that the prolonged impact winter would end.
