The Tor-ho is the most fearsome beast in the mountainous regions of Va-nah, the inner surface world of the Earth's moon. It's a reptilianoid predator, about the size of a mountain lion and with an appearance also somewhat reminiscent of a feline creature, although predominantly reptilian. It has curved fangs and its vocalizations have been described as a most horrible sound, like a combination of shrieks and moans. As a predator, it is notable for its persistence and extreme aggressiveness, as it seemingly never abandons a target, even after being severely injured in fight.
