Benlithulan
From Tardis Wiki, the free Doctor Who reference
The Benlithulans were a species which Krem-ling had fed upon, along with the Heemies, Worgs and Suasion Norbs. Marsalla mentioned them to the Fourth Doctor when he asked if Krem-ling had always looked as he did now, an elderly male humanoid. (PROSE: The Vampires of Crellium)
