Wemics are also called liontaurs, felitaurs, and cencats.
The human part of a wemic has feline characteristics -- always around the eyes and ears, and perhaps in the nose and teeth as well. Males are generally represented as having long mane-like hair.
Wemics are excellent hunters and fighters. They do not make settled homes, but generally follow the herds they hunt for food. Some have compared them with the aboriginal people of the central plains of North America.
Wemics are larger and stronger than humans. A wemic can leap up to 50 feet with a running start. Their front claws are sharp, and they can fight with both claws and weapons at the same time. Some gamers have suggested that they are keen of eye and ear, that they can roar, that they can rake with their back claws, and so on, but these options are not universally used in most role-playing games.
It may be hard to imagine what wemics are like, since they are not only different in race, but in form. Take sitting, for example. When a wemic must be still for a time, telling stories around a fire, pausing for a meal, waiting for a friend, or just to take a brief rest, the Wemic commonly assumes a posture in which his hindquarters rest on the ground as his front legs remain straight and his forepaws stay flat on the earth. This they call sitting. This is different from a Wemic sprawling (both hind and forequarters on the ground, but with torso upright) or laying down.
A nomadic, stone-age folk, wemics are often represented as barbaric, illiterate, and uncivilized; they are famous for being highly superstitious. Others would describe Wemics as nature-oriented people with a rich tradition of oral history -- they live close to the earth and are in tune with the magical forces around them.
An early reference to wemics can be found in a set of "Monster Cards Set 3," a first edition Dungeons and Dragons game product released in 1982. Another reference can be seen in Sierra Studios Quest for Glory III computer role-play game, here referred to as liontaurs. But these references are by no means conclusive, and it would be wonderful to be able to cite earlier ones.
