The cows of the great horned tyrs from Killorn were for meat and milk and leather, and trudged meekly enough behind the wagons. But the huge black bulls were wicked and had gored more than one man to death. Still Kery had gotten the idea of using them in battle. He had made iron plates for their chests and shoulders. He had polished their cruel horns and taught them to charge when he gave the word. No other man in the army dared go near them, but Kery could guide them with a whistle. For the men of Broina were warlocks. They snorted in the twilight as he neared them, stamping restlessly and shaking their mighty heads. He laughed in a sudden reckless drunkenness of power and moved up to his big lovely Gorwain and scratched the bull behind the ears. "Softly, softly," he whispered, standing in the dusk among the crowding black bulks. "Patient, my beauty, wait but a little and I'll slip you, O wait, my Gorwain." Spears blinked in the shadowy light and voices rumbled quietly. The bulls and the hests snorted, stamping and shivering in the thin chill wind flowing from the lands of night. They waited. Presently they heard, faint and far, the skirling of war pipes. But it was not the wild joyous music of Killorn, it was a thin shrill note which ran along the nerves, jagged as a saw, and the thump of drums and the clangor of gongs came with it. Kery sprang up on the broad shoulders of Gorwain the tyr and strained into the gloom to see. Over the rolling land came marching the invaders. It was an army of a thousand or so, he guessed with a shiver of tension, moving in closer ranks and with tighter discipline than the barbarians. He had seen many armies, from the naked yelling savages of the upper Norlan hills to the armored files of civilized towns, yet never one like this. _Dark Landers_, he thought bleakly. _Out of the cold and the night that never ends, out of the mystery and the frightened legends of a thousand years, here at last are the men of the Dark Lands, spilling into the Twilight like their own icy winds, and have we anything that can stand against them?_ They were tall, as tall as the northerners, but gaunt, with a stringy toughness born of hardship and suffering and bitter chill. Their skins were white, not with the ruddy whiteness of the northern Twilight Landers but dead-white, blank and bare, and the long hair and beards were the color of silver. Their eyes were the least human thing about them, huge and round and golden, the eyes of a bird of prey, deep sunken in the narrow skulls. Their faces seemed strangely immobile, as if the muscles for laughter and weeping were alike frozen. As they moved up, the only sound was the tramp of their feet and the demon whine of their pipes and the clash of drum and gong.
