Bosk
“The bosk, without which the Wagon Peoples could not live, is an oxlike creature. It is a huge, shambling animal, with a thick, humped neck and long, shaggy hair. It has a wide head and tiny red eyes, a temper to match that of a sleen, and two long, wicked horns that reach out from its head and suddenly curve forward to terminate in fearful points. Some of these horns, on the larger animals, measured from tip to tip, exceed the length of two spears.”—Nomads, 5
Kaiila
“The mount of the Wagon Peoples, unknown in the northern hemisphere of Gor, is the terrifying but beautiful kaiila. It is a silken, carnivorous, lofty creature, graceful, long-necked, smooth-gaited. It is viviparous and undoubtedly mammalian, though there is no suckling of the young. The young are born vicious and by instinct, as soon as they struggle to their feet, they hunt. It is an instinct of the mother, sensing the birth, to deliver the young animal in the vicinity of game. I supposed, with the domesticated kaiila, a bound verr or a prisoner might be cast to the newborn animal. The kaiila, once it eats its fill, does not touch food for several days.
“The kaiila is extremely agile, and can easily outmaneuver the slower, more ponderous high tharlarion. It requires less food, of course, than the tarn. A kaiila, which normally stands about twenty to twenty-two hands at the shoulder, can cover as much as six hundred pasangs in a single day’s riding.
“The head of the kaiila bears two large eyes, one on each side, but the eyes are triply lidded, probably an adaptation to the environment which occasionally is wracked by severe storms of wind and dust; the adaptation, actually a transparent third lid, permits the animal to move as it wishes under conditions that force other prairie animals back into the wind, or, like the sleen, to burrow into the ground. The kaiila is most dangerous under such conditions, and, as if it knew this, often uses such times for its hunt.”—Nomads, 13-14
Sleen
“As we passed among the wagons I leaped back as a tawny prairie sleen hurled itself against the bars of a sleen cage, reaching out at me with its six-clawed paw. There were four other prairie sleen in the cage, a small cage, and they were curling and moving about one another, restlessly, like angry snakes. They would be released with the fall of darkness to run the periphery of the herds, acting, as I have mentioned, as shepherds and sentinels. They are also used if a slave escapes, for the sleen is an efficient, tireless, savage, almost inescapable hunter, capable of pursuing a scent, days old, for hundreds of pasangs until, perhaps a month later, it finds its victim and tears it to pieces.”—Nomads, 28
Verrs and Vulo
"Kamchak and I dismounted and, from outside the circle, watched the four chief haruspexes of the Wagon Peoples approach the huge altar in the center of the field. Behind them another four haruspexes, one from each People, carried a large wooden cage, made of sticks lashed together, which contained perhaps a dozen white vulos, domesticated pigeons. This cage they placed on the altar. I then noticed that each of the four chief haruspexes carried, about his shoulder, a white linen sack, somewhat like a peasant's rep-cloth seed bag...
"Each of the four haruspexes then, after intoning an involved entreaty of some sort to the sky, which at the time was shining beneficently, suddenly cast a handful of something--doubtless grain--to the pigeons in the stick cage.
"Even from where I stood I could see the pigeons pecking the grain in reassuring feeding frenzy."--Nomads, 172
