This forgettable show was a mid-season replacement for CBS in early 1983.
A full-on stereotypical medieval sword-and-sorcery fantasy adventure, this show was set in the time of King Arthur's Court. Jeff Conaway (Bobby from Taxi) held the starring role. The Wikipedia plot description:
The legendary kingdom is ruled by good King Baaldorf and Queen Lattinia. Their daughter, Ariel, is engaged to Prince Erik Greystone, who becomes Camarand's champion against a neighboring kingdom ruled by evil Prince Dirk Blackpool. Erik is assisted by his servant, Marko, the strongest man in the kingdom and often hindered by his ne'er-do-well playboy brother, Justin.Interestingly, most episodes were directed by Bill Bixby. Only eight episodes were produced.
