regor opened his fingers, and the sword fell to the ground. It was shiny with the red liquid, which, if it wasn't actually blood, sure looked like it. He ran his sword hand across the front of his shirt, leaving a big red stain. Suddenly he felt sick.

He turned on his heel and walked away from the sword, from the blood balls, from the Underlanders who were now beginning to talk in excited voices. Word of what he'd just done must have been spreading around the arena, because people were rushing toward the cannon area. He could feel them beginning to press in on him, and someone, Mareth maybe, called his name. It was becoming hard to breathe.

Suddenly Ares was there before him. "I know a place" was all he said. Gregor automatically climbed on his back, and they took off. He could hear several people calling for him as they flew out of the stadium, but Ares didn't stop. They headed not in the direction of Regalia, but into the tunnels opposite the entrance to the city.

"You will want light," Ares said, angling in toward a row of torches on the tunnel wall, and Gregor reached out and snagged one. In the torchlight, his hand glistened wet and red. He looked away.

Ares dove off into a side tunnel that forked repeatedly. Eventually they arrived at a small underground lake flanked by dozens of caves. The bat dove into one with a narrow entrance. Inside, the cave opened up into a wide space. Large crystal formations grew down from the high ceiling. Gregor slid off Ares's back and onto the stone floor.

He pressed his forehead into his knees and let his breathing return to normal. What had happened back there? How had he hit all fifteen blood balls? He'd been running sword drills with Mareth and nothing unusual had happened, but when those blood balls had started flying at him...

"Did you see? Did you see what I did?" he asked Ares. He had seen some bats flying around the arena that morning, but he hadn't noticed Ares.

The bat sat motionless for a moment, then answered. "You broke all the blood balls."

"I hit them all," Gregor said, still trying to remember it. "But I don't even know how to use a sword."

"Apparently you learn quickly," said Ares, and somehow that made Gregor laugh a little. He looked around the cave. There were food supplies, blankets, spare torches.

"What's this place? Like, your hideout?" Gregor asked.

"Yes, my hideout," said Ares. "At one time it was also Henry's. We came here when we did not want to be around others. Now it is less my hideout than my home."

The implication of what the bat was saying began to dawn on Gregor. "So, you don't live with the other bats anymore? I thought when I bonded with you it made things okay again — about Henry and all."

"It spared me from official banishment. But no one save Aurora and Luxa will speak to me," said Ares.

"Not even Vikus?" Gregor asked, forgetting his own problems for a minute.

"Well, yes, Vikus. But he will speak to anyone," Ares said without much enthusiasm.

He had had no idea things were so bad for the bat. If he hadn't been banished physically, he had been banished socially from his world. And then when Gregor had shown up again, all he'd done was order him around. "Look, I really am sorry about yesterday," he said. "I was mad and scared about Boots, and I took it out on you."

"I was angry, too, about many things that have little to do with you," said Ares.

So, it was better between them. But Gregor still felt like Ares was a stranger.

"How'd you hook up with Henry, anyway?" he blurted out. Maybe it wasn't polite to ask, but it was the main thing Gregor wanted to know.

"Henry chose me because I was wild and known to disobey many of the rules of my land. I chose Henry because I was flattered and he was royal and under his protection I knew I could be absolved of many things," said Ares. "It was not all bad. We flew well together and shared many of the same tastes. In most ways, we were suited to each other. In one, we were not."

So among bats Ares had been some bad-boy rebel type. Of course, that was the kind of bat Henry would pick. Gregor had picked Ares, too, because the bat had risked everything to save his life — but would he have chosen him if the circumstances hadn't been so extraordinary? He didn't know.

There was a rustling of wings at the cave entrance, and Aurora flew in with Luxa.

"We knew you would be here!" cried Luxa. She bounced off Aurora and almost danced across the floor, clapping her hands together. "Was it not wonderful? Did you see it? Did you see the look on Stellovet's face?"

"As if she had a mouth full of vinegar," Aurora purred, apparently also in a good mood.

"Why?" said Gregor.

"Why? Because of you and the blood balls!" Luxa said, as if he were dense. "She thought to make you look like a fool, and instead you hit the total! Almost no one has ever done this, Gregor! It was brilliant!"

For the first time, Gregor felt a tinge of pride in his accomplishment. Maybe he had overreacted, because of the fake blood and all. Maybe he'd actually just done a really cool thing, like running the table in pool, or pitching a no-hitter in baseball. "Yeah?" he said.

"Of course! And I have not seen Stellovet so put out since the picnic!" said Luxa, giggling at the memory.

The bats both began to make a "huh, huh, huh" sound, and it took a moment for Gregor to realize they were laughing.

"Oh, Gregor, you should have seen it. Vikus forced us all to go on this picnic with my Fount cousins because he thought it would help us get along better. And Stellovet kept pretending she heard rats, and making Nerissa terrified. So Henry tricked her into eating moth cocoons. She spent the whole afternoon picking silk out of her teeth and saying, 'Ah will noth forgeth thiseth!'" Luxa said, doing a pretty great imitation of someone with their mouth full of silk.

"How'd he get her to eat cocoons?" Gregor asked, both amused and grossed out.

"He told her they were a delicacy reserved only for royalty and he could not offer her any. So of course she stole a handful and stuffed it in her mouth," said Luxa.

"Henry could trick her into anything," Ares said, followed by a few more "huh, huh, huhs." And then suddenly his laughter faded. "He could trick all of us."

A cloud seemed to fall on the bats and Luxa. Henry had treated them far worse than he had treated Stellovet.

"Whatever Henry was wrong about, he was right about my Fount cousins," Luxa said grimly. "Especially Stellovet. She dreams of Nerissa and me dying because she thinks Vikus would be made king then and she, as his granddaughter, would be a princess."

They were all quiet for a time, then Aurora piped up on a more positive note. "Gregor's feat will be good for you, Ares."

"We shall see," said Ares.

"It will. It will do you no harm to have a bond who can hit the total," said Luxa. "No one will dare ignore you now."

Gregor hoped this was true. It didn't seem like Ares had much of a life.

Suddenly Ares's and Aurora's heads shot up. Luxa listened a second and then leaped onto Aurora's back. They were gone in a flash.

Gregor could hear some kind of horn blowing in the distance. It had a high, wailing pitch. "What is it?"

"It is a warning, Overlander. You had best mount up," said Ares. Gregor grabbed a torch and threw his leg over Ares's neck. They were immediately airborne.

"Warning? What kind of a warning?" he asked as they swerved out over the lake.

Ares spoke calmly, but his muscles were tense. "It means that rats have entered Regalia."
