The black prism

Nonetheless, he poured perfect yellow luxin into the forms. The real Gavin couldn't have done this: he wasn't a superchromat, he couldn't draft a perfect yellow. But Gavin couldn't go halfway. There was no "good enough" with yellow luxin; if it weren't drafted perfectly, it would dissolve. Simple as that.

Something rocked the wall, and Gavin almost fell from his perch. Someone steadied him, and he saw that Tremblefist was standing beside him, holding him up. A moment later, he heard the delayed rumble of distant artillery.

"I've got you," Tremblefist said. He wasn't quite as big as his older brother, but he too had worked with Gavin a long time. He must have seen the glazed, stupefied look in Gavin's eyes, because he said, "Our own ca

More of King Garadul's artillery began landing in the field, most of it far short of Brightwater Wall. The sound of the enemy culverins became a thunderstorm in the distance. Gavin gathered his will and kept drafting. He didn't realize that he was weaving on his feet until he felt Tremblefist's big hands close on his shoulders. Several other Blackguards pressed close.

"Raise the cowl!" General Danavis yelled.

As yellow luxin splashed from Gavin's hands into the forms below him, he felt the wall shudder as each section of the cowl swung into place on counterweights. The cowl was his architect's invention. Basically, it was a removable roof for use during artillery bombardment. There were plenty of times when an open roof was preferable-to gather rainwater, when it was unbearably hot, or when men had to carry great loads or carts had to pass down the length of the wall. But during a bombardment, it would shield defenders from howitzers and mortar fire. The wall's own artillery was left free to fire on the same basic defensive design as an arrow slit-easy to fire out at a wide angle, but requiring a direct hit from the other side to put it out of commission.

"What the hell is that?" Tremblefist breathed. Gavin wouldn't have even heard him except that the man was basically holding him up. And Tremblefist didn't talk to himself much.

Gavin looked up, giving himself a small break, and looked over the plain.

The army was rumbling ever closer, catching up with their culverins. In front of them were teams setting up the howitzers-the defenders still hadn't fired a single shot, a fact that had General Danavis screaming at the nearest crews.

But that wasn't what had Tremblefist cursing. In front of the main army, drawing even with the advance ca

They would be at the wall within four minutes at the most.

Four minutes. Gavin looked at his half-formed gate. If he didn't worry about hinges, if he just sealed the damn thing to the wall itself, it was possible. Maybe. He looked up at the sun, gathering power. It was less than an hour until sunset. The festivities for Sun Day's Eve would start as soon as the last ray of sun disappeared from the horizon. Whether the attackers were heretics or pagans or faithful, they wouldn't fight during Sun Day. Sun Day was holy even to the gods Lucidonius had driven out.

If they could hold off the attackers for that one hour, they had a chance. And Sun Day would give them the time they needed to reinforce the gates and get supplies and guns in place.

One day. One hour. Four minutes that would determine the course of this war. It came down to this. Gavin was not going to quit. He had four minutes left in him.

The culverins on the wall finally answered those out in the field, but the shots were wild, not even close to the field artillery emplacements or the charging color wights. And more of King Garadul's shots were hitting the wall itself, each rebounding off the yellow luxin with a crunch and a whine and a splay of yellow light as the wall absorbed the blow and healed itself.

The forms Gavin was filling with luxin were three-quarters full, washing him in the invigorating scents so close to mint and eucalyptus, but he was tiring anyway. He looked out to the color wights. Not even two minutes left.

Orholam, I'm trying to do something good here. Great purpose, Orholam. Selfless and all that. You want people to be selfless, right?

Tremblefist handed Gavin off and was shouting orders down to the Blackguards on the ground. General Danavis was ordering troops to the gate and to form in ranks behind the wall. The crowd was begi

Flashes of magic bloomed in front of him. The color wights had spotted him. They were throwing missiles and fire and everything they could think of, but his Blackguards were deflecting it all.

Gavin kept drafting. The color wights were only two hundred paces out now, ru

Drafting the last of the yellow luxin to fill the last form, Gavin pulled the threads together in his hand. He was going to make it! He was sealing the luxin when a ca

In two seconds, the gate flashboiled into nothingness and disappeared-and so did Garriston's hope.

Chapter 73

Gavin collapsed. Or he would have, if two Blackguards hadn't caught him and dragged him away from the brink. He wanted to fight them, to stand up, but he was so lightheaded he couldn't even make words.

He missed the first clash, right below his perch, but he heard it, felt it. The yells of men and women bracing themselves, giving voice to fear and rage, honing their will for their drafting. Then waves of heat and the shock of impact, armor popping, men and wights grunting. Then, screams, always screams.

"Where are my muskets?! I ordered those brought here two hours ago!" General Danavis was screaming. Swearing. He was standing ten paces from Gavin, looking through the murder holes and machicolations at the battle beneath the arch of the gate. His soldiers were blinking at him. Out of twenty men, only two had muskets. "Fire, damn you!" he shouted at them. "You, and you, go find muskets. Now!" Then he was gone, screaming at the artillery crews.

The Blackguards pulled Gavin to the edge of the wall. The cowl on the wall meant there were only a few places open on either the front or the back. They found one where the cranes pulled in goods. A Blackguard bichrome drafted a blue-green slide all the way to the ground.

"What are you doing?" Gavin managed.

"We're taking you to safety, sir." Then the man jumped onto the slide.

Gavin was looking through the bright hallway formed by the bo
