He was considering the possibilities on his return to the fort when a soldier in the armor of the Realms of the Sun hailed him and informed him that Their Highnesses Parahan and Soudamini desired his company at breakfast. By the time Briar left Parahan and Souda, they had equipped him for any fighting they might encounter as they got the villagers to the safety of the temple fortresses. He now had three horses assigned for his use, extra packs, a tent, an armored vest, riding gauntlets, leather riding breeches, and an armored cap with a tassel of bronze eagle feathers. He also had a short, potbellied rider named Jimut, who had been assigned to care for Briar’s horses, tent, and even Briar himself.

He and Jimut had just dumped everything in Briar’s room when Rosethorn banged on the door. Briar could hardly believe what he saw when he opened up. Rosethorn looked fresher and brighter than she had in a couple of years. There was an extra gloss to her short-cropped hair. Even the natural red of her lips was more vivid than it had been in a long time.

“What are you gawping at, boy?” Her voice was louder and crisper, as if she had more wind in her lungs. Briar forgot himself and hugged her. She pushed him away. “What has gotten into you? Don’t think I’ve forgiven you for your rudeness to First Dedicate Dokyi last night!”

He grinned at her. “Never crossed my mind,” he reassured her.

Rosethorn looked at Jimut. “And who’s this?”

“Jimut, this is my teacher, the nanshur Rosethorn,” Briar said. He’d been lucky that Souda had found a man who spoke tiyon, since Briar had only a scattering of words in Banpuri. “She’ll be riding with us.”

Jimut pressed his palms together before his face and bowed deeply to Rosethorn. On their walk to the fort Briar had tried to explain that it was important to be polite to her.

“Whatever he told you, I’m much worse,” Rosethorn said.

Jimut kept his palms together and bowed again.

Rosethorn made a harrumphing noise and looked at Briar. “Bring a seed ball and some strong-grow potion,” she ordered. “Captain Rana has horses and guards waiting. We’re going to block the pass.”

“May I come?” Jimut asked. “If I am to attend Nanshur Briar —”

Briar sighed. “It’s just Briar.” He’d already said it to Jimut twice.

“I should take every chance to become used to his sort of magic,” Jimut continued politely.

“I have no problems with that,” Rosethorn said. “Only Briar, if we can move this along? We need to root them more deeply than usual, and I want to get it over with.”

“Evvy?” Briar asked.

“She would rather take a bath, she says. She has seen us do this before.”

They were out the door with Rosethorn before she had time to get testy. She said nothing, sinking into a distant, thoughtful mood as they joined Sergeant Kanbab and a squad of ten soldiers at the stables.

As they rode past the camp, they saw that everyone was now up and busy shining armor, sharpening weapons, bundling crossbow bolts, and doing up packs. In the open ground between the tents and the river, archers practiced their shooting while spearmen and swordsmen dueled under the eyes of their commanders. The cavalry jumped their horses over obstacles in unison on the plain. Refugees were arriving: They carried children and belongings, or fetched them in carts and on the backs of mules and yaks as they climbed to the fort.

Once they reached the narrow place in the pass where the road first entered the river gorge, Rosethorn emerged from her deep silence. “Sergeant, take your people over to that rock,” she yelled over the roar of the fast-moving water. “If you’d hold our horses until we’re done?”

Kanbab nodded and motioned for her people to take the animals as Briar, Jimut, and Rosethorn dismounted. Jimut stayed back as the mages went into the bottleneck where the hills were closest to the road.

The task was easily done. Briar sprinkled strong-grow potion on the seed balls held by each of them, but the seeds were already quivering before the liquid touched them. The balls had soaked in the wakefulness and swift growth of the others used in the fighting on their way to the fort. Now it took just a whisper from Rosethorn for them to leap to the ground. The cloth burst, showering seeds everywhere. Plants slammed roots into the earth and sprouted even as Rosethorn and Briar walked forward with their water flasks. By the time they had emptied the water over the scattered seed, the growing vines were up to their shins. The green whips did not try to snag the two mages, but those would be the only people the vines left alone. Thorns an inch long showed on the lowest parts of the stems as the vines rose and sprouted more branches. Their various flowers budded and bloomed, then scattered still more seed in a burst of air.

Rosethorn and Briar had withdrawn to the clear ground near Jimut by the time the first blossoms showed. Everyone could see that green stems had crawled across all of the open ground between the rise of stone to the hills and to the river. They could hear the rustle as petals and leaves unfurled and heavy stems wove together with their neighbors.

Kanbab, who had at least seen something like this before, offered Rosethorn her flask. Rosethorn took a gulp of butter tea, grimaced, and passed the flask to Briar. He took two good drinks, having acquired a taste for the local beverage, and returned the flask to Kanbab with a quiet thank-you. He never took his eyes from the barrier, feeling with his power for any weaknesses. Rosethorn left that to him as the kind of basic work a junior mage ought to attend to.
