The sayce is a xenoc creature native to the jungles of Amarisk, on the frontier world of Lalonde. It is a dog-analogue (and is a similar size to a large Earth canine) but has a distinctly catlike appearance, with a strong, streamlined body covered in jet-black scales. The sayce has six-clawed paws and a wedge-shaped head, with flat, triangular ears, green-tinted eyes, a blue tongue and powerful jaws equipped with sharp fangs.
It is a very intelligent animal (scoring higher in intelligence than terrestrial dogs) but is also extremely aggressive, not averse to tackling a human or members of its own species. Surprisingly, the sayce is a good mimic and able to learn and speak human words; it is thus able to communicate with humans in a rudimentary way.
Certain bars in Durringham organise savage fights to the death between sayce — a good “baiter” can earn plenty of cash for its human owner. In these fights, experience counts as much as physical strength, and a veteran sayce often has a good chance of winning. An older sayce has a generally battered and scarred appearance; ageing also has an effect on the sayce's hide, which becomes flecked with blue spots.
In a similar way to some terrestrial creatures such as cats and dogs, the sayce is capable of displaying a sensitivity to energies not usually perceived by humans; at least on one occasion a sayce has correctly identified a group of possessed as being somehow different to normal humans, and has then expressed appropriate fear and caution.
