Corianda

From Tardis Wiki, the free Doctor Who reference

Corianda was the daughter of King Gavin XXIII and the sister of Japonica.

Corianda and Japonica were very friendly with Jamie McCrimmon when he and the Second Doctor were on their planet. After the Doctor and Jamie helped to restore their father to the throne, Corianda and Japonica wanted Jamie to stay. (PROSE: Twin Piques)
