Split Infinity

Neysa blew an angry note through her horn and surfaced. Stile dropped back to her back. He yanked off two more eels that had fastened to him while he was below, as if his cessation of humming had made them bold.

Neysa cut to the edge of the river and found her footing. She charged out of the water. Stile had taken round six.

North of the river was a slope rising into a picturesque mountain range. The highest peaks were cloud-girt and seemed to be snow-covered. Surely she was not about to essay the heights!

She was. She galloped up the slope, the wind drying out her hair and his. What an animal she was! An ordinary horse would have been exhausted by this time, but this one seemed to be just hitting her stride.

The pace, however, was telling; Stile could feel her body heating. Horses, with or without horns, were massive enough to be short on skin surface to radiate heat.  Therefore they sweated, as did man—but still it could take some time to dissipate the heat pollution of over-exertion. She would have to ease up soon, even if her muscles still had strength.

She did not. The slope increased; her hooves pounded harder. One-two, three-four, a good hard-working gallop. She was not even trying to shake him off, now, but she surely had something excellent in mind. The grain-grass turf gave way to fields of blue and red flowers and goldenrod. More rocks showed, their rugged facets glinting cruel deep gray in the sun.  The trees became smaller. Wisps of fog streamed by.

Stile craned his neck to look back—and was amazed.  Already the Meander River was a small ribbon in the distance, far below. They must have climbed a vertical kilometer! Suddenly the air seemed chill, the breeze cutting. But the unicorn was hot; again small sparks flew from her feet as the hooves struck the rocky ground. Fine jets of vapor spurned from her nostrils.

Vapor? Stile squinted, unbelieving. Those were jets of fire!

No, impossible! No flesh-creature could breathe out fire. Living tissue wasn’t able to—

Stile nudged forward, freed one hand, and reached ahead to approach the flame he thought he saw. Ouch!

His fingers burned! That was indeed fire!

All right, once more. This was a magic land. He had accepted that, provisionally. The laws of physics he had known did not necessarily apply. Or if they were valid, they operated in different ways. Horses generated heat —so did unicorns. Horses sweated—this creature remained dry, once she had shed the river water. So she got rid of excess heat by snorting it out her nostrils in concentrated form. It did make sense, in its particular fashion.

Now the air was definitely cold. Stile was naked; if they went much higher, he could be in a new sort of trouble. And of course that was the idea. This was round seven, the trial of inclement climate. Neysa was not suffering; she was doing the work of running, so was burning hot. The cold recharged her.

Stile got down as close to his mount as he could. His back was freezing, but his front was hot, in contact with the furnace of Neysa’s hide. This became uncomfortable. He was trying to sweat on one side and shiver on the other, and he couldn’t turn over. And Neysa kept climbing.

Could he steer her back down the hill? Unlikely; trained horses moved with the guidance of reins and legs and verbal directives—but they did it basically be-cause they knew no better. They were creatures of habit, who found it easiest to obey the will of the rider.  This unicorn was a self-willed animal, no more tract-able than a self-willed machine. (Ah, Sheen—what of you now?) If he did not like her direction, he would have to get off her back.

So he would just have to bear with it. He had to tame this steed before he could steer her, and he had to stay on before he could tame her. He found himself humming again. It seemed to help.

Neysa’s feet touched snow. Steam puffed up from that contact. She really had hot feet! She charged on up the side of a glacier. Ice chipped off and slid away from her hooves. Stile hummed louder, his music punctuated by his shivering.

Crevices opened in the glacier. Again the unicorn’s feet danced—but this time on a slippery slope. Her hooves skidded between steps, for their heat melted the ice. Those sparks were another heat-dissipating mechanism, and though the snow and ice had cooled the hooves below sparking level, there was still plenty of heat to serve. Her body weight shifted, compensating for the insecure footing, but a fall seemed incipient.  Stile hummed louder yet. This was no miniature Game-mountain, under a warm dome, with cushioned landings for losers. This was a towering, frigid, violent landscape, and he was afraid of it.
