Cantus shook his head. “It’s hard to get within sight of the horde during daylight, even for fliers. There is a constant battle for control of the air with those wasp-men they’ve got. I can spare only a handful of fliers to use for reconnaissance, and they’ve returned reports varying from three hundred thousand to ten times that number. So far, none of them have turned north for Phrygia. They seem to be intent on pursuing Princeps Attis.”

“They don’t dare do anything else,” Tavi said. “If the High Lords get a chance to catch their breath, they can still be very, very dangerous to the vord.”

Fidelias cleared his throat. He pointed a finger toward the far end of the northeastern causeway, the one that ended at Garrison. “Offhand, I’d say your pessimistic scout was the most likely to have been correct in his observations.”

“Why?”

“The geography,” Fidelias said. “Princeps Attis is seeking advantageous ground. Calderon may suit his purposes.”

“Why say that?” Varg rumbled.

Tavi began to ask Cyricus to expand the sand table’s view of the Calderon Valley, only to find that the stuttering young man was already in the process of doing it. Tavi made a mental note to himself: If he survived this war, he simply had to offer the young man a job. Initiative like that was uncommon.

“Ah, thank you, Master Cyricus,” Tavi said. “Princeps Attis is leading the vord into a funnel,” Tavi said. “Once they’ve passed the western escarpments and entered the Calderon Valley, they’re going to be forced to crowd in closer and closer. Sea on the north, impassable mountains in the south.”

“Neutralizing the advantage of numbers,” Varg growled.

“In part. But he’s also going there because my uncle has turned the place into a bloody fortress.”

Fidelias glanced up at Tavi, frowning.

“You saw the holders of the Calderon Valley throw up a siege wall in less than half an hour at Second Calderon,” Tavi said. “Now consider that my uncle’s had the next best thing to five years to prepare.”

The Cursor lifted his eyebrows and nodded. “Still. If the numerical disparity is that great, the Shieldwall itself might not be enough. And if he’s leading the vord into a trap, he’s going to be stuck in it as well. There won’t be any way for him to retreat any farther. There’s nowhere else he can go.”

“He knows that,” Tavi said, frowning. “And the vord know it, too. Which is why he did it.”

Cyricus frowned. “Y-your Highness? I d-don’t understand.”

“He isn’t so much leading them into a trap as he is playing the anvil to our hammer.” Tavi touched the sand table, made a minor effort of will, and added multiple rectangles to the landscape, representing his own forces. Then he began to shift the pieces as if they’d been part of a game of ludus.
