Saduj is found in Ultima V, sneaking around the roof of Castle Britannia in the night, acting suspiciously. At first Saduj didn't say much. However, after the Avatar revealed to be a member of the Oppression by saying the password "IMPERA", Saduj became much more talkative. Saduj was a spy sent by Lord Blackthorn to get possession of the Sandalwood Box, to ensure that Lord British would be sealed in the dungeon Doom permanently. He then offered his services to the Avatar's party.
