It had turned out to be magnetic. A low-strength magnet in the window, when moved too far from a sensor in the frame, set off the alert. She’d solved this by using a plastic letter with a tiny magnet in it from her preschool alphabet set. Moving it a little bit every time she tried to open the window, until one time she opened it and no one showed up outside to make sure she was okay.
Now she slid her magnet to the correct spot, manually undid the window, and lifted Muskrat carefully out. She climbed out after, pulling the frame closed behind her. Muskrat chuffed and started off along the path to the edge of the palace, and Teresa followed behind.
It had been too long. It was time to go see Timothy.
She’d found the secret tunnel almost a year before. It was hidden by a rock in a group of ornamental trees. She’d initially thought it might have been dug out by some local animal. There was a kind of underground wasp that left holes that looked similar to it when they died and their hives collapsed. It had turned out to be part of a flood relief system to make sure the gardens never drowned in heavy rain. It led under the walls of the State Building compound and into a small field beyond. Intellectually, she knew that a normal girl might not have gone down the tunnel with the spearmint smell of broken ground and the thin coat of slime. She had pushed through easily, joyfully even, and a few dark moments later had found herself on the far side of the perimeter and free for literally the first time in her life.
She’d gone walking. Exploring. Discovering. Engaging in developmentally appropriate rebellion. And, most importantly, she’d made her first real friend.
Animals had made the path she and Muskrat followed through the forest. Bone-elk and ground pigs and pale, shovel-faced horses, none of which had any relationship to Sol system elk or pigs or horses. She walked down the path, her hands in her pockets. Muskrat bounded through the dappled shade, barking at sun-birds and smiling a wide tongue-lolling grin when they hissed back. It had been too long since she’d been to see Timothy, and she had too much she wanted to talk with him about. It wouldn’t all fit in her head at the same time.
The forest at the edge of the State Building thickened at first, the gloom growing around her, and then the land began to rise. She started feeling her breath get deeper, and it felt good. Before long, the path led out of the trees entirely and into a clearing at the skirt of the mountain. She knew from her studies that the mountain wasn’t natural but a kind of artifact of some long-forgotten alien project. Like a sandcastle, but tall enough that the top seemed to touch the clouds. Not that she’d ever been to the summit. Timothy’s cave was much closer than that.
The entrance was in a little canyon not far from the clearing where she’d first come upon him. Muskrat knew the way better than she did. She walked down the pale sand along the path carved by water that had long since dried. Wide, fresh Labrador paw prints marked her way. By the time Teresa left the last scraggly trees behind, the dog was already at the bend that led there, barking and wagging her tail.
“I’m coming,” Teresa said. “You’re such a pain.”
Muskrat shrugged off the insult, turned, and bounded ahead like a puppy. Teresa didn’t see her again until she stepped under what looked like an overhanging shelf of sandstone and into the deeps of the cave. The natural stone gave way almost immediately to the soft glow of the cavern. Stalactites hung from the ceiling like bright icicles, and the walls were built with swirls and shapes in them like a seashell and a Euclidian proof had joined together and become an architect. Teresa always had the feeling that the walls changed to greet her, but of course she was only there when she was there, so she couldn’t be certain.
A flock of tiny, glowing gnats flowed past her like a wave. Like she was underwater. The air smelled thick and astringent, and a coolness radiated from the walls.
Soft padding sounds came from ahead. Not human sounds, and not Muskrat either. The footsteps weren’t even animal, not really. The repair drones were a little smaller than Muskrat, with dark, apologetic-looking eyes and multiply jointed legs. Totally alien, but they were the closest things to canine friends that Muskrat had, and the real dog ran around them, yipping excitedly and sniffing their rears as if there were anything doglike to smell back there. Teresa shook her head and moved forward. The repair drones made their query tone, trying to intuit whether Muskrat wanted something. The drones were surprisingly good at judging at least the rough intentions of humans. Real dogs still seemed to baffle them.
The repair drones, the light gnats, the slow, creeping, wormlike stone diggers were all in the weird space between life and not-life. Designed by an intelligence that evolutionary forces had taken in a direction very different from humanity. They weren’t exotic to her at all. As far as Teresa was concerned, they’d always been there, just like that.
“Hello!” Teresa called. “Are you here?”
The words echoed weirdly out of the deepness. “Hey, Tiny. I wondered when you were coming back.”
Timothy’s part of the cave was like another phase change. Nature to alien to human, if not exactly the kind of human residence she was used to. A backpack reactor leaned against the wall, thick yellow power cords going to a wooden rack of neat, well-maintained machines. She recognized the yeast incubator and the emergency recycler from her tours of the early settlements. Other decks she didn’t know. All together, it was enough that Timothy could live like a monk and a wise man in his mountain for more than a human lifetime. His bed was a cot against one wall with a blanket of woven polycarbonate that seemed never to show wear. He didn’t have a pillow.
The man himself sat next to a length of wood, a knife in his thick, callused hand. A pile of thin, curled slivers rested between his feet where they fell as he carved. He was bald and pale, with a thick, bushy white beard, wide shoulders, and arms with muscles like ropes.
She’d come across him months ago during one of her first excursions. She’d been trying to get high enough on the mountain to see the State Building, and there he’d been, eating his lunch and drinking from a scarred ceramic water purifier. He’d looked like nothing so much as an old cartoon of an enlightened guru meditating on a mountaintop. If there had been any threat in his smile, she might have been scared of him. But there wasn’t, and she wasn’t. And anyway Muskrat had liked him immediately.
“Sorry,” she said, sitting on the edge of his cot. “I’ve been busy. I have a bunch of new things I’m studying. What are you working on?”
Timothy considered the half-carved wood. “I was going for a marking gauge. I’ve got one already, but it’s a little big for the fine work.”
“And you can’t have too many tools,” Teresa said. The phrase was something of a joke between them, and Timothy grinned.
“Damned straight. So what’s up?”
Teresa leaned forward. Timothy frowned and put down the wood and the knife. She didn’t know where to start, so she started with her father’s plan to train her up.
He had a way of shifting his attention so that she felt like he was actually listening, not just preparing a reply in his head and waiting for her to stop talking. He focused on her the way he did on the wood he carved or the food he cooked. He didn’t judge her. He didn’t quiz her. She never worried that he would be disappointed with what she said.
