“Brother, I can’t; did you not hear my promise to Dmitrii?”

“Damn Dmitrii; he thinks only of his crown.”

“Sasha, do not be afraid for me.”

“I am though,” he said. “For your life and for your soul.”

“They are both in my keeping, and not yours,” she said gently. But a little of the wildness had gone from her expression. She took a deep breath. “I will not forget what you said. I am your sister, and I love you. Even wandering in darkness.”

“Vasya,” he said, his voice heavy with reluctance. “Better even the winter-king than that beast.”

“You both have an exaggerated idea of my brother’s good qualities,” said the Bear, just as Vasya snapped, “The winter-king is not here!” In a calmer voice, she went on, “For it is not winter. I must use the tools I have.”

The mare shook her mane and stamped, obviously eager to be gone.

“We are going,” said Vasya to her, as though the mare had actually spoken. Her voice was a little ragged. She pulled away. “Farewell, Sasha.” She swung to the mare’s back and looked down at her brother’s troubled face. “I won’t forget what you told me.”

Sasha merely nodded.

“In three days,” said Vasya.

Then the mare bounded forward, bucking, and his sister was at once lost in the night. The devil looked back, winked at Sasha, and followed.

VASYA LEFT OLEG WHERE she’d met him, at the edge of the scrubby steppe where his men were encamped, a day’s march from Kulikovo.

Pozhar cow-kicked the Grand Prince of Ryazan as he slid down her golden flank and said very definitely, That is the last time I carry one of his kind ever again. He is heavy.

Oleg said, at the same moment, “I will leave riding the horses of legend to you, witch-girl. It is like trying to ride a thunderstorm.”

Vasya could only laugh. She said, “If I were you, I’d delay your march to join Mamai. They are going to have a bad few days. I will see you at the battle.”

“God willing,” said Oleg Ivanovich, and bowed.

Vasya inclined her head, turned Pozhar, and then they were back on the Midnight-road.

MOTHER OF GOD, I am tired of darkness, Vasya thought. Pozhar’s sure feet made nothing of the night, the changing landscape, but there was no comfort in the surge of the mare’s running, her jutting withers and swift strides. Vasya rubbed her face, and tried to focus her mind. Her brother’s warning had shaken her. He was right. All the anchor-stones of her life had gone: home and family and sometimes it seemed her very self, lost in the fire. Even Morozko had gone, not to return until the snow fell. Now her companion in the darkness was a creature whose nature was madness given flesh. But sometimes he sounded ordinary, even sensible, and every time that happened she had to remind herself to keep up her defenses.

Now the Bear was pacing the golden mare, beast-shaped. “Men will not keep their word,” he said.

“I do not recall asking for your opinion,” she snapped.

“Better for chyerti to fight them, before they destroy us,” the Bear went on. She could hear the echo of men screaming in his low voice.

“Or better yet, let the Russians and the Tatars destroy each other.”

“Dmitrii and Sergei will keep their word,” she said.

“Have you ever thought what meddling in their war will cost you?”

he said. “What price Dmitrii’s promise and his admiration? I saw the look in your eyes when Dmitrii called you princess.”

“Is the prize not worth the risk?”

“That depends,” said the Bear, as they ran through Midnight. “I am not sure you know what you’re risking.”

She didn’t answer. She didn’t trust his seeming-sense any more than she trusted his wickedness.

THE LAKE WAS DARK in the moonlight, rippling black, white dazzles on the crests of the waves. No long, terrifying journey on foot for her this time; Vasya found the lake swiftly, as though her blood remembered it.

She and Pozhar and the Bear burst out of the trees and found themselves beside the great stretch of moonlit water. Vasya’s breath caught in her throat and she slid down the mare’s shoulder.

The horses were grazing where she’d last seen them, near the shore. This time they didn’t run from her but stood, ghostly in the cold mist of early autumn night, raised their flawless heads and looked. Pozhar pricked her ears and called softly to her kin.

The witch’s empty house stood black and still on its tall posts, on the other side of the field. Still a grim ruin, the domovaya asleep once more, perhaps, waiting in her oven. Vasya let herself briefly imagine the house warm with firelight, with laughter, her family close, the horses—a great herd—grazing in the starlight outside.

One day.

But that night, she was there neither for the house, nor for the horses.

“Ded Grib!” she called.

The little chyert, glowing green in the dark, was waiting for her in the shadow of the great oak. He gave a small cry, ran toward her, then halted halfway. Either he was trying to look dignified, or the Bear made him nervous, Vasya could not tell.

“Thank you, my friend,” Vasya said to him, and bowed. “For asking Pozhar to come to me. You both saved my life.”

Ded Grib looked proud. “I think she likes me,” he confided. “That is why she went. She likes me because we both glow at night.”

Pozhar snorted and shook her mane. Ded Grib added, “Why did you come back? Are you going to stay now? Why is the Eater with you?” The mushroom-spirit looked suddenly fierce. “He is not to kick over any of my mushrooms.”

“That depends,” said the Bear pointedly. “If my brave mistress does not give me something better to do than run to and fro in the dark, I will happily kick over all your mushrooms.”

Ded Grib bristled. “He is not going to touch anything of yours,”

said Vasya to Ded Grib, glaring at the Bear. “He is traveling with me now. We came back for you because I need your help.”

“I knew you couldn’t do without me!” cried Ded Grib, triumphantly. “Even if now you have allies that are bigger.” He gave the Bear a very hard look.

“This is going to be a terrible war,” the Bear interjected. “What damage do you expect to do with a mushroom?”

“You’ll see,” said Vasya, and offered her hand to the little mushroom-spirit.

MAMAI’S ARMY WAS STRUNG out along the Don. The vanguard was already settled at Kulikovo, the reserves encamped in stages for a great distance to the south, ready to march up at first light. Moving softly through Midnight, Vasya and the mare and the two chyerti capped a small rise, and peered through the trees at the host below.
