A chamberlain served in Richard the Lionheart's court at Palestine.
In 1190, he recognised the clothing worn by the First Doctor and Vicki Pallister as belonging to the palace. When he confronted the Doctor, the Doctor convinced him that Ben Daheer had bought the clothing from Thatcher, who had stolen it from the palace. The chamberlain paid Daheer for the clothes and chased after Thatcher.
The Chamberlain later found some appropriate clothes for Vicki, after he found out that she was a girl. (TV: The Crusade)
