tay you!" cried Vikus, as Luxa, Henry, and Mareth sprang up, swords in hand. "Stay you!"

The rat regarded the three armed humans with amusement. "Yes, stay you or I shall be forced to move, and that always puts me in an ill humor," he said languidly.

Luxa and Mareth stopped uncertainly, but Henry ignored Vikus's command and lunged at the rat. Without moving another muscle, the rat flicked his tail. It cracked like a whip knocking the sword from Henry's hand. The blade spun across the stone floor and slammed into the cavern wall. Henry gripped his wrist in pain.

"The hardest lesson for a soldier to learn is to obey orders he believes are wrong," said the rat philosophically.

"Take care, lad, or you shall end up like me, stripped of any respectable rank and warming your shabby old hide at the fire of your enemies." The rat nodded at the old man. "Vikus."

"Ripred," said Vikus with a smile. "We have just commenced dining. Will you join us?"

"I thought you'd never ask," said Ripred, pushing himself off the wall and slouching over to the fire. He squatted back on his haunches next to Solovet. "My dear Solovet, how kind of you to fly out to greet me. And with a war on, too."

"I could scarcely have missed an opportunity to break bread with you, Ripred," said Solovet.

"Oh, come now, you know perfectly well you only tagged along to wheedle information out of me," said Ripred. "And to gloat over your victory at the Flames."

"I destroyed you," said Solovet with glee. "Your army turned tail and ran howling into the river."

"Army," snorted Ripred. "Why, they were as much an army as I am a butterfly. I'd have stood a better chance fighting with crawlers." The rat looked at Temp and Tick, who were cowering against the wall, and sighed. "Present company excepted, of course."

Boots frowned and toddled over to Ripred. She pointed her chubby finger up at him. "You mouse?"

"Yes, I'm a mouse. Squeak, squeak. Now shoo-shoo back to your little bug friends," said Ripred, picking up a hunk of dried beef. He tore off a piece with his teeth and noticed Boots hadn't moved. He pulled back his lips to reveal a row of jagged teeth and gave her a sharp hiss.

"Oh!" said Boots, scurrying to her roaches. "Oh!"

"Don't do that," said Gregor. The rat turned his glowing eyes on him, and Gregor was shocked by what he saw there. The intelligence, the deadliness, and, most surprisingly, the pain. This rat was not like Fangor and Shed. He was much more complicated and much more dangerous. For the first time in the Underland, Gregor felt completely out of his league. If he fought this rat, he wouldn't stand a chance. He would lose. He would be dead.

"Ah, this must be our warrior," said Ripred softly. "How very like your daddy you are."

"Don't scare my sister," said Gregor, trying to keep his voice steady. "She's only a baby."

"From what I hear, she's got more guts than the lot of you combined," said Ripred. "Of course, courage only counts when you can count. I'm presuming the rest of you can count, and will be screwing your courage to the sticking place any minute now."

The rat glanced around at Luxa, Mareth, and Henry, who were keeping their distance. The bats were extending and folding their wings, unsure of what to do. "Well, come on, then, isn't anyone else hungry? I hate dining alone. It makes me feel so unloved."

"I did not prepare them, Ripred," said Vikus.

"Clearly," said the rat. "Clearly my arrival is an unexpected pleasure." He went to work on his beef bone, making an awful scraping sound.

"Meet you, Ripred the gnawer," said Vikus to the group. "He shall be joining the quest as your guide."

There was a quick breathy sound, as half of those gathered inhaled sharply. A long pause followed in which no one exhaled. Gregor tried to make sense of what Vikus had announced so calmly. A rat. He was leaving them in the hands of a rat. Gregor wanted to object, but his throat had frozen.

Finally Luxa spoke up in a voice hoarse with hatred. "No, he shall not. We do not travel with rats."

" 'The Prophecy of Gray' requires it, Luxa," said Solovet. "One gnawer beside."

"'Beside' could mean anything," snarled Henry. "Perhaps we leave the gnawer dead 'beside' us."

"Perhaps you do. But having witnessed your last attack, I doubt it," said Ripred, starting on a wedge of cheese.

"We have killed five rats since midday," said Luxa.

"You mean the idiots that I handpicked for cowardice and ineptitude? Oh, yes, bravo, Your Highness. That was a masterly piece of combat," said Ripred, his voice dripping with sarcasm. "Do not flatter yourself you have yet fought a rat."

"They themselves killed Fangor and Shed," said Mareth bravely.

"Well, then, I stand corrected. Fangor and Shed were excellent fighters, on the rare occasions they were sober," said Ripred. "However, I expect they were outnumbered and somewhat thrown by the arrival of our warrior. What say you, Warrior? Do you refuse to go with me as well?"

Gregor looked into Ripred's mocking, tortured eyes. He wanted to refuse, but if he did, could he ever find his dad?

As if following his thoughts, Vikus spoke up. "You need Ripred to guide you to your father. These tunnels are unmapped by humans. You would never find your way without him."

Still, he was a rat. Gregor had only been in the Underland a few days and he already despised rats. They had killed Luxa's and Henry's parents, imprisoned his father, and almost eaten him and Boots. He felt a kind of power surging through him when he thought of how much he hated them. But if all rats were bad, who was this strange creature staring at him from across the fire, offering to be their guide?

"So, what's in this for you?" said Gregor to Ripred.

"A fair question," said Ripred. "Well, Warrior, I am planning to overthrow King Gorger and I need you to help me."

"By doing what?" said Gregor.

"I don't know," admitted Ripred. "None of us does."

Gregor rose and caught Vikus by the arm. "I have to talk to you alone," he said. The anger in his voice surprised even himself. Well, he was angry! The rat was not part of what he'd agreed to. This was not what he'd signed on for.

Vikus took Gregor's mood in stride. Maybe he had expected it. They walked about twenty yards away from the group. "So, how long have you had this plan with the rat?" asked Gregor.

Vikus thought a moment. "I am not sure exactly. Perhaps two or so years. Of course, it was all dependent upon your arrival."

"How come you didn't tell me about it before?" demanded Gregor.

"I do not believe in giving people more information than they can handle," said Vikus.

"Who says I can't handle it? I can handle it!" said Gregor, obviously not handling it.

"Perhaps you can, at least more easily than Luxa and Henry. I may well have told you if we had ever finished our discussion of 'The Prophecy of Gray,'" said Vikus. "No doubt you would have asked, and, yes, I may well have told you."

Gregor pulled the prophecy from his pocket and said, "Let's finish it now." He searched out the part of the prophecy where they'd left off.

One gnawer beside and one lost up ahead.

"So Ripred is the 'gnawer,' and my dad is the 'one lost up ahead,'" said Gregor. He read on.

And eight will be left when we count up the dead.

"What does that mean?" asked Gregor, pointing to the line.

"If you add up all the players in the prophecy, two over, two under, two fliers, two crawlers, two spinners, one gnawer, and one lost, you have twelve," said Vikus gravely. "By the end of the quest, only eight will remain alive. Four will be dead. But no one knows what four."

"Oh," said Gregor, stunned. He'd heard the words before, but they only registered now. "Four of us dead."

"But eight alive, Gregor," said Vikus gently. "And perhaps a world saved."

Gregor couldn't deal with that part now, wondering who would be left standing at the end of the day. He pushed on to the final stanza of the prophecy.

The last who will die must decide where he stands.

The fate of the eight is contained in his hands, so bid him take care, bid him look where he leaps, as life may be death and death life again reaps.

"I don't get this last part," said Gregor.

"Nor do I, nor does anyone. It is very cryptic. I believe no one will fully understand it until the final moment has arrived," said Vikus. "Gregor, it is not pleasant, it is not easy, but it is essential, what I ask you to do. Essential to you, if you wish to find your father. Essential for my people, if they are to survive."

Gregor felt his anger ebbing and fear filling the empty spaces it left. He took another tack. "I don't want to go with that rat," said Gregor, almost pleading. "He'll kill us."

"No, you cannot judge Ripred by what you know of other rats. He has wisdom unique in any creature. Things were not always so bad between humans and rats. When Solovet and Ripred and I were younger, we lived in relative peace. Ripred would see that restored, but King Gorger wishes all humans dead," said Vikus.

"So, you're saying Ripred's a good rat," said Gregor, choking on the words.

"If he were not, would I trust my granddaughter to his care?" asked Vikus.

"Your granddaughter?" said Gregor blankly. "Luxa's mother was my daughter, Judith," said Vikus.

"You're her grandpa? Why does she call you Vikus?" asked Gregor. These people were so weird and formal. How could he not have known that?

"It is our way," said Vikus. "Look after her. If this is hard for you, know it is torture for Luxa."

"I haven't said I'm going yet!" said Gregor. He looked into the old man's eyes. "All right, I'm going. Is there anything else I need to know that you haven't told me?"

"Only this: Despite what I said, I knew you were the warrior from the first moment I spied you," said Vikus.

"Thanks. Great. That's very helpful," said Gregor, and they returned to the group. "Okay, Boots and I are going with the rat. Who else is in?"

There was a pause. "Where goes the princess, go we," said Temp.

"What say you, Luxa?" said Vikus.

"What can I say, Vikus? Can I return to our people and tell them I withdrew from the quest when our survival hangs in the balance?" said Luxa bitterly.

"Of course you cannot, Luxa. This is why he times it so," said Henry.

"You could choose to -- " started Vikus.

"I could choose! I could choose!" retorted Luxa. "Do not offer me a choice when you know none exists!" She and Henry turned their backs on Vikus.

"Fliers?" said Solovet, as Vikus seemed to have lost the ability to talk.

"Aurora and I go with our bonds," muttered Ares.

"Then it is settled. Come, Mareth, we are needed at home," said Solovet.

A distraught Mareth quickly made up packs of food for the members of the quest. "Fly you high, all of you," he said in a strained voice, and climbed on his bat.

Solovet mounted her bat and unrolled her map. While Ripred helped her work out the safest route back to Regalia, Vikus moved to Henry and Luxa. Neither of them would turn to look at him.

"I would not part this way, but I understand your hearts. Perhaps one day you will be able to forgive me this moment. Fly you high, Henry. Fly you high, Luxa," said Vikus. He waited for a response, but none came. He turned and climbed heavily onto his bat.

As miserable as Gregor felt about being dumped with a rat, his heart ached for Vikus. He wanted to scream at Luxa, "Say something! Don't let your grandpa fly off like this! Four of us aren't coming back!" But the words caught in his throat. Part of him wasn't ready to forgive Vikus for abandoning them, either.

"Fly you high, Gregor the Overlander," said Vikus.

Gregor struggled with how to respond. Should he ignore Vikus? Let him know that none of them, not even an Overlander, could forgive him? Just as he had steeled himself against replying, Gregor thought of the last two years, seven months, and, was it fifteen days now? There were so many things he wished he'd said to his dad when he'd had the chance. Things like how special it was when they went on the roof at night and tried to find stars. Or how much he loved it when they took the subway out to the stadium to watch a baseball game. Or just that he felt lucky that out of all the people in the world, his dad was his dad.

He didn't have room inside him for any more unspoken words. The bats were rising into the air. He only had a second. "Fly you high, Vikus!" he yelled. "Fly you high!"

Vikus turned back, and Gregor could see tears shining on his cheeks. He lifted up a hand to Gregor in thanks.
