Monstrous cave bears, essentially vegetarian and only limited hunters, were twice the weight of the smaller brown or black bears, which also preferred an omnivorous diet that often included grass, though the white bear of the icy coasts subsisted on meat from the sea. Vicious wolverines and steppe polecats took their toll of smaller animals, including the vast number and variety of rodents, as did the sinuous sables, weasels, otters, ferrets, martens, minks, and stoats that became ermines in snow. Some foxes also turned white, or the rich gray called blue, to match the winter scenery and hunt in stealth. Tawny and golden eagles, falcons, hawks, crows, and owls snatched unsuspecting, or unlucky, small prey on the wing, while vultures and black kites cleaned up the leavings of others on the ground.

The great diversity and size of the animals that lived on those ancient steppes, and their bonus of exaggerated and richly enhanced appendages and supplementary growths, could only be sustained by an environment of exceptional quality. Yet it was a frigid, sere, demanding land surrounded by mountain-high barriers of ice and bleak oceans of frozen water. It seemed a contradiction that such a harsh environment could provide the richness that was necessary for the lavish growth of the animals but, in fact, the environment was entirely right for it. The cold, dry climate fostered the growth of grass and inhibited the growth of trees.

Trees, such as oaks or spruces, are luxuriant growths, but they take a long time and ample moisture to mature. Woodlands may feed and support a range of other plants and animals, but trees need resources to maintain themselves, and they do not encourage the development of multitudes of large animals. A few animals may eat nuts or fruits and others may browse leaves, or even twig tips from a tree, but bark and wood are largely inedible, and grow back slowly once destroyed. The same energy and soil nutrients put into an equal weight of grass will feed many, many more, and the grass will constantly renew itself. A forest may be the quintessential example of rich, productive vegetable life, but it was grass that gave rise to the extraordinary and abundant animal life, and it was the complex grassland that supported and maintained it.

Ayla was feeling uncomfortable, but she wasn't sure why. It was nothing specific, just a strange, edgy feeling. Before they started down the high hill, they had watched storm clouds gathering over the mountains to the west, seen flashes of sheet lightning, and heard distant rolling thunder. The sky above, however, was a clear, deep blue, with the sun still high, though past the zenith. It was unlikely to rain nearby, but she didn't like thunder. The deep rolling roar always reminded her of earthquakes.

Maybe it's just that my moon time should start in a day or two, Ayla thought, trying to dismiss the feeling. I had better keep my leather straps handy, and the mouflon wool Nezzie gave me. She told me it was the best padding to use when traveling, and she was right. The blood washes right out in cold water.

Ayla had not seen onagers before, and with her thoughts turned inward, she wasn't paying attention as they proceeded down the slope. She thought the animals she saw in the distance were horses. But when they got closer, she began to notice differences. They were slightly smaller, their ears were longer, and their tails were not a flowing tress of many hair strands, but a shorter, thin shaft covered with the same kind of hair that was on their bodies, with a darker tuft at the end. Both kinds of animals had erect manes, but the onagers' were more uneven. The coats of the animals in the small herd were a light reddish brown on their backs and sides, and a much paler, almost white coloring underneath, even on their legs and muzzles, but they had a dark stripe along their backbones, plus another across their shoulders, and several bands of the darker shade on their legs.

The young woman compared them with the general coloring of the horses. Though her dun coat was a shade lighter than average, with a rich golden yellow tone, most steppe horses were a similar neutral grayish brown shade and generally resembled Whinney. Racer's deep brown color was unusual for his breed. The mare's stiff thick mane was a dark gray, and the color extended down the middle of her back to her long, loose tail. Her lower legs were dark, too, almost black, and above that, only the bare suggestion of stripes showed on her upper legs. The bay stallion's color was too dark to show the black feral stripe that ran down his backbone very well, but his black mane, tail, and legs followed the typical pattern.

To someone who was knowledgeable about horses, the body conformation of the animals ahead was somewhat different, as well, yet they did seem to be horses. Ayla noticed that even Whinney showed more interest than she usually did at the sight of other animals, and the herd had stopped grazing and was watching them. Wolf was interested, too, and had assumed a stalking posture, ready to take out after them, but Ayla signaled him to stay. She wanted to observe them. One of the onagers suddenly voiced a sound and the woman noticed another difference. It wasn't a neigh, or a whinny, but rather a more strident braying sound.

Racer tossed his head and neighed an answer, then gingerly stretched his head forward to sniff at a large pile of fresh dung. It looked and smelled like horse dung to Ayla, when she rode up alongside Jondalar. Whinney nickered and sniffed the pile, too, and as the odor wafted up to her a while longer, Ayla thought she detected a faint undercurrent of something else, perhaps from somewhat different food preferences.

"Are those horses?" she asked.

"Not exactly. They're like horses, the way elk are like reindeer, or moose are like megaceroses. They're called onagers," Jondalar explained.

"I wonder why I haven't seen them before."

"I don't know, but they do seem to like this kind of country," he said, inclining his head in a gesture that indicated the rocky hills and sparse vegetation of the arid, semidesert upland plains they were riding through. Onagers were not a cross between horses and asses, though they appeared to be, rather a unique and viable species, with some characteristics of both, and extremely hardy. They could subsist on even coarser food than horses, including bark, leaves, and roots.

When they got closer to the herd, Ayla noticed a pair of young ones and couldn't help smiling. They reminded her of Whinney when she was young. Just when the wolf yelped to get her attention.

"All right, Wolf. If you want to chase those… onagers" – she said the unfamiliar word slowly, getting used to the sound – "go ahead." She was pleased with the progress she was making in training him, but he didn't like staying in one place for long. He was still too full of puppyish enthusiasm and curiosity. Wolf yelped and bounded after the herd. With a startled burst, they raced away with a sustained speed that soon left the young, would-be hunter behind. He caught up with Ayla and Jondalar as they were approaching a broad valley.

Though the valleys of rivers carrying the silt of slowly eroding mountains still cut across their path, the land was falling off gradually toward the basin of the Great Mother River delta and Beran Sea. As they were traveling south, the summer was deepening, and warm winds caused by the passage of atmospheric depressions across the sea added to the increasing temperatures of the season, and to weather disturbances.

The two travelers no longer wore outer clothes, not even when they first got up. Ayla thought the cool, crisp air of early morning was the best time of the day. But the late afternoon was hot, hotter than usual, she thought, wishing for a nice cool stream to swim in. She glanced at the man riding a few paces ahead. He was bare to the waist, and barelegged, wearing only a loincloth. His long blond hair, pulled back into a thong at the nape of his neck, had lighter streaks from the sun, and was darker where the sweat had made it wet.
