Killoran

The Killoran were a species of wolf-like humanoids.

Biology
Killorans were sentient, canine humanoids who resembled a six or seven-foot-tall cross between a wolf and an ape. They had fur covering their bodies, and extremely strong teeth. Due to their tremendous strength, Killorans were much in demand as construction workers. (PROSE: The Doomsday Manuscript, The Stone's Lament)

Killorans and humans had similar reproduction techniques that allowed for sexual interaction to take place. Hybrids were also possible. (PROSE: The Squire's Crystal) Killorans grew faster than humans, and were larger than a human baby at birth. (PROSE: The Glass Prison) Around their fourth year, young Killorans suffered from delirium, diarrhoea, and vomiting. (PROSE: Mentioning the War)

Killoran blood could be used to cure heart conditions in humans, though it was dangerous in the long term and caused headaches and a short temper. (AUDIO: Thicker Than Water)

Culture
Since the Killoran language couldn't be spoken by humans, Killorans living or working among humans generally adopted a pseudonym. They tended to favour names drawn from Earth history, especially names of military leaders. (PROSE: The Doomsday Manuscript) Killorans taught their young to build and climb a pile of building materials. (PROSE: Misplaced Spring)

History
A Gallifreyan legend maintained that Pandora, a long-ago Lady President of Gallifrey, had a female Killoran bodyguard. (AUDIO: Lies)

Killorans invaded the planet Világ, a planet populated by humans. (AUDIO: Arrangements for War) The Killorans left the planet ravaged. (AUDIO: Thicker Than Water)
