Chapter 22
Gregor squinted into the ashy gray light and finally made out the nibblers. They were walking single file down a long curved path that began at what looked like the mouth of a tunnel high in the rocks and that led to a pit at the base of the volcano. On one side the path ran along the edge of a sheer cliff with sharp rocks at the base. A stone wall ran along the other side of the path, blocking the view of the pit from their sight. It wasn't until the nibblers were almost at the bottom that they realized where the rats were sending them.
The nibblers who had reached the pit began to squeal out warnings to those following them. Gregor could see the alarm spreading up the path. Mice turned and tried to force their way back up, some literally crawling over the backs of the others to try to reach the tunnel at the top. A handful made it only to be driven back by rats. Then the mice began to shriek as a large boulder was rolled into place, sealing the mouth of the tunnel. They threw themselves against the boulder but could not budge it.
"Let us go!" cried Luxa, jumping to her feet.
"And do what?" asked Ripred, stepping in front of her. "You, all of you, you've got to stop running into dangerous situations without using your heads! There is no faster way to get killed!"
"We can carry them out of the pit to safety!" said Luxa.
"Yes, a handful of them. But there are hundreds trapped down there. Do you not think the rats might notice an airlift going on? And then what? We lose the one element we have in our favor. Surprise," said Ripred.
"Then what do you want us to do?" demanded Luxa. "Wait for the volcano to smother them in lava?"
"I want you to think about it a moment!" snapped Ripred.
"Vis for volcano," Boots reminded everyone. "And valentine." She poked Ripred on the haunch with her scepter. "Valentine!" Ripred sighed. "Why are you here?"
A gust of wind swept by, drawing everyone's attention. "Oh, great. The currents are starting up again," thought Gregor. If they became too strong, the bats wouldn't be able to navigate them. At least they were clearing the air a little. One overriding current seemed to be blowing out of a nearby cave. It was sweeping the ashy haze toward the nibblers and giving Gregor his first breath of clean air in hours.
"Look, the nibblers are taking action," said Howard.
The mice had overcome their initial panic and were organizing themselves to carry out an escape plan. They had begun to build a pyramid by bracing themselves along the far wall of the pit. A single row of mice formed the base. Others were swarming onto their backs swiftly. The pyramid was rising before their eyes.
"That's smart. A pyramid," said Gregor.
"No, it is the Isosceles Maneuver," said Cartesian.
Gregor looked at him. For the first time since Cartesian had joined them, the mouse seemed lucid. "What's that?" Gregor said.
"It is not a true pyramid, for it has three, not four, points. Rather, they aspire to mimic a two-dimensional triangle," said Cartesian.
"Oh," said Gregor. It seemed to him that at home almost anything with people standing on top of other people was called a pyramid, but he didn't feel like arguing the point with Cartesian, especially after all the mouse had been through.
"See, they have a plan. Let's work with it," said Ripred. "What they need is someone to hold that path if the rats come through."
"Then we will do so," said Luxa.
"Agreed. Temp, watch the pups. The rest of you mount up," said Ripred.
Gregor was about to jump onto Ares when Ripred stopped him. "No, I'll need him to get to the path. Ride with someone else and change over when he drops me off."
"Here, Gregor," said Howard. He extended a hand and pulled Gregor up behind him on Nike.
"We should wait until the boulder begins to move. That will give us time to reach the path but not alert the rats to our presence beforehand," said Luxa.
"Good. Very good. Now you are thinking," said Ripred. "Everyone wait for it, as she says."
They sat watching, tense and poised for takeoff.
The mouse pyramid was nearing the top of the pit. Soon they would be able to begin freeing themselves. Still the boulder didn't budge.
"If there were to be lava, would we have some warning?" asked Howard.
"Generally, I believe there's a rumbling, some sort of sound," said Ripred. "Although I am no expert."
The first nibblers began to climb over the edge of the pit. The escape plan was working.
"Maybe the rats won't come back," said Gregor. "Maybe they didn't figure the mice could get out."
The mice were sending the pups up now. Trying to save them first. When five little ones had reached the top, a pair of full-grown mice began to corral them away from the pit as fast as possible. No rats appeared to interfere.
Back in the tunnel, they watched silently for a few more minutes.
Then Luxa broke the silence. "Something is wrong. Why would the rats allow this?"
"They wouldn't," said Ripred. He paused. "Unless they were expecting something else to do their work for them."
"But there's no lava. The volcano isn't even erupting," said Gregor. Suddenly Temp began to wave his antennas, his feet stepping nervously on the ground. "Not lava, it be, not lava," said the cockroach.
