Hemal

Hemal was a Time Lord who served as Lord Cardinal on the High Council of Gallifrey. He sent a distress call to the Fifth Doctor to investigate in a Time Lord murder. It was soon found the murder had been committed by a vampire. (COMIC: Blood Invocation)

Behind the scenes
Discounting Kevin Lindsay's yellowface portrayal of K'anpo Rimpoche in 1974, Cardinal Hemal became the first Time Lord depicted as a person of colour, in 1994.
