Rigelian
From Tardis Wiki, the free Doctor Who reference
Rigelians were a near-human species on good terms with the Time Lords. They got the loan of K9 from the Time Lords when the Rigelian Seventh Fleet disappeared. K9 liaised with a male Rigelian fleet commander, who sternly focused K9 on the task of discovering why the Seventh Fleet had been subjected to vanishment. (AK9: K9 and the Time Trap)
- Writer Dave Martin gave no other details about the species.
