––––––––
Altia was entering the Drifter System, and it never failed to take her breath away. The most obvious feature, of course, was the light sail. It had been visible for hours as she approached, a unique landmark within the galaxy.
The sail was an enormous self-supporting artificial construct, the product of megascale astroengineering. It was positioned next to the star, Drifter Prime, at a position chosen by its architects to balance gravitational attraction towards the star and radiation pressure away from the star. This made the radiation pressure of the star asymmetrical, and this created thrust. The star was essentially tethered to the sail, being pulled along on its own solar wind. The thrust and acceleration was very slight, but the star's fuel was enough for billions of years. Drifter Prime had been traveling for a very long time indeed.
That wasn't all though. There was an entirely artificial planet in orbit, which had been dragged along by its parent star, constructed to be carried through the galaxy forever, or even journey between galaxies. The entire artificial planet could be thought of as a kind of passenger compartment in a galactic-scale vehicle, the Drifter, but a passenger compartment that could carry billions of passengers.
Altia's transport, a small science ship called Panoto 5, dove towards the artificial planet, which grew to fill her forward view screen. The government of Tarazet was doing its best to learn about the entire site, but their efforts were focused on one single location. This area being investigated by the Science Ministry was the largest feature of the planet's surface, the Rift. It was a kind of canyon that was cut two kilometers deep in the planet's mechanical crust. Panoto 5 descended on gravitics, towards a complex of buildings, the gray of the human architecture standing out against the bronze of Drifter architecture. From a distance, the human buildings looked like nothing more than gray fungus on the face of a bronze sculpture.
Panoto 5 was directed to a landing pad jutting from the side of one of the larger human structures and touched down. Through the view ports Altia could see that Brax, her second in command, had come out to meet her.
Brax was an AI encased in a humanoid body
“Hi there Brax,” Altia yelled as she descended the ramp of Panoto 5, “What's been happening here while I've been away?”
“Haven't you been reading my reports?” Brax said.
His face didn't have as many muscles as a human's, but he was unmistakably smiling, teasing her.
“I like it when you give me an executive summary,” Altia said, “I like the sound of your voice.”
"Then come with me," Brax said, "And we'll do some show and tell."
Brax and Altia wandered through the Science Ministry installation, and then out into the tunnels below the surface of the artificial planet. They had to pause briefly for Altia to put on an environment suit, the tunnels were not pressurized and there was no breathable atmosphere, but Brax didn't stop talking.
The tunnels they were walking through came from a median period, according to current theories, and represented what Altia considered the pinnacle of Drifter culture.
“We have found more evidence that this planet was a holy site,” Brax said, “I'm increasingly of the opinion that the Drifters used it as a center of pilgrimage and worship.”
“Usually it is the pilgrims who journey,” Altia mused, “Not the temple they visit. And the scale of it. An entire planet as a holy site. It is mind boggling.”
The lighting in the corridors was human, switching on as they approached and switching off again as they passed on to the next area where Brax wanted to do a show and tell.
“We believe this area,” Brax pointed, “Is an attempt to repair damage. Notice the lack of hieroglyphs.”
“There are some, though,” Altia mused.
“Yes,” Brax allowed, “But all the other surfaces here are covered with them. There must be some reason that this area is smoother.”
Brax took her to another area, happily explaining all the newest developments as he led the way.
“I know you are very interested in the Drifter language,” he said.
“Languages,” Altia corrected.
Brax nodded. He knew Altia suspected that the hieroglyphs carved everywhere represented more than one language. The same symbols, she thought, had very different meanings depending on the language using them, and the languages were probably all jumbled up together. A Drifter would be able to recognize immediately which language was being used. The way she could distinguish between Trader, Tarazeen and Banathan, even though they used essentially the same set of symbols.
“I have found an ancient symbol,” Brax said, “Another of the basic root symbols.”
"That's wonderful," Altia couldn't keep excitement from her voice, "Could be another breakthrough."
"We can only hope."
They reached the point in the corridor where the new symbol had been discovered. Altia bent to examine it.
“It's in a dark corner,” she said.
Brax projected a large hologram of the area of the wall they were standing beside, from a projector on his chest. The robot turned the projection and zoomed in on the symbol they were interested in. Altia reached out to touch the hologram version of the symbol, though, of course, there was nothing physical beneath her fingertips, just the immaterial surface of the hologram. She traced the edges of the symbol thinking about why that symbol had been chosen to sit on this innocuous looking patch of wall.
“Interesting,” she said, “The closer to the root they are, the less abstract they are.”
The symbol looked like waves, and she had the idea of flow, though she was aware this was just a subjective notion that had occurred to her human mind and might not have anything remotely in common with the life of the Drifters.
"Fascinating, isn't it?" the robot mumbled.
Altia went over to the patch of wall, bending at the waist to examine the actual physical symbol in its context. The robot didn't take its eyes off the hologram in front of it.
"I wonder what these conduits in here were for," Altia said, pointing at some structure in the wall of the tunnel, "We know so little about their technology. They could be for power, life support, or... or... delicious snacks, for all I know."
There were three heavy conduits, right next to the symbol.
"Flow," she mumbled to herself.
Altia stared at the conduits, and at the symbol. The conduits were dead, serving no purpose. Most of the planet's systems were inert, with only maintenance online. But whether they were in operation at the moment or not, there would be a certain direction to their flow. She stood back and tried to trace the flow with her mind.
Then she saw it, after years of her life spent studying this long-dead language, she saw it. She understood.
She turned to Brax, who was still examining the holographic enlargement of the symbol.
"Brax, please project architectural schematic oblique four, for sector gold nine" she asked him.
A spiderweb of blue lines representing walls, floors and ceilings sprang into life, projected from the robot's chest, slowly turning.
"And overlay that with character set G60," she said.
Spidery green lines appeared, outlines of a subset of the alien hieroglyphs, superimposed on the floor plan. Altia's face lit up. There was the correlation she had been looking for. The hieroglyphs with longer bars were in longer corridors. The variations in size of elements of the characters weren't to do with available space, or with graphic design, they held meaning. A whole new level of meaning that nobody had guessed was present was mapped onto the dimensions of the writing.
“Have you found a connection?” Brax asked.
“I think I have,” Altia said.
“If we could decipher these hieroglyphics,” Brax said, “It would help us immeasurably in working out the secrets of Drifter technology.”
“Yes it would,” Altia said, with a smile, “Yes it would.”
***
Over the next few weeks Altia found much more meaning modulated within the dimensions of the characters. She saw a numbering systems, indications of position, status and relationships. The language rapidly unfolded itself to her. But she still couldn't assign a meaning to any of the characters that would be like a word. Except perhaps the word “flow”, the more she thought about it, the more convinced she became.
The history of the language was there in front of her. She could see early root forms develop into more and more complex forms. The Drifter scribes would write in any direction, depending on the space available, and wrote left to right, right to left, up to down and down to up, and combinations of these. The only way to determine which way to read a text was to look at the asymmetrical characters. She more and more began to suspect that these asymmetrical characters represented lifeforms. One in particular recurred over and over. She wondered if this one character might be a representation of a Drifter.
There was already a huge amount of data on the patterns and interrelationships of the language, but the only item of vocabulary she had discovered was the word flow, which she was becoming increasingly convinced was her first Drifter word. But with just one word, a whole language could be decrypted.
For an entire week, she focused on similar characters and discovered another, its opposite, blockage. With these first cornerstones she went on to build outwards, gradually unlocking the meaning of the language. She was so happy with her progress, so confident that she was right, that she had to share it, to get news of her discovery out. First of all though she wanted to tell her superior, Shivia.
Altia was sitting in her office, in a temporary building bonded to the floor of a large chamber deep below the planet's surface, when she decided to make the call. Shivia's holographic avatar appeared in mid air in the center of the room. It was a simple departmental logo crest with her name and rank written below. When Shivia accepted the call, this logo went fuzzy at the edges and was replaced by a hologram of Shivia herself, standing life-size on the floor a few paces away.
"Altia?" Shivia said.
"Hello," Altia replied.
"What's this about?"
"Something huge. I think I have taken the first steps towards a decipherment."
Shivia didn't reply. Shock could clearly be seen on her face, despite the poor resolution of the field-grade military hologram communicator.
"Have you gone mad? Nobody has made progress in a hundred years."
"I hesitate to make this call, but I am convinced."
"I will come to you," Shivia said.
The line went dead, Shivia's hologram replaced by the departmental crest, slowly turning in the air. Altia shut off the communicator. If her boss was coming to see her work, she'd better have something impressive to show her.
She noticed that her diary was being remote accessed. The diary opened up, displaying all its little boxes, with each little box representing a time slot and they were all color coded and full. Altia saw all her appointments being canceled, all her time slots going white. Then one slot in ten days time colored red. The words, Meeting with Shivia, appeared.
"It looks like I have ten days to get my ideas together."
Shivia must have been off world. It was the only explanation of the length of time she had allowed before the meeting. Altia was grateful for all the extra time she could get. She spent the entire ten days decrypting texts collected from around the artificial planet. There was so much information, her vocabulary was filling so fast. With each new translation, correlations could be made that allowed further translations. By the time Shivia arrived, she had pages of deciphered text to show her. The text had gaps. It was often difficult to interpret, but there was no doubt it was real.
Shivia arrived unannounced via the largest of the corridors leading off from Altia's camp site. She was brought by grav sled from wherever her spaceship had landed. She was accompanied by a team of scientists and a pair of armed guards. They didn't have heavy weapons and they weren't wearing combat armor, but it was odd to see armed personnel down on the planet, although they were common enough up in orbit.
"Well hello Altia," Shivia said, emerging from the grav sled, "I've been hardly able to sleep for wondering at the marvels you would have to show me."
"I hope you aren't disappointed."
"I hope for the same thing," Shivia said, a slight menace to her voice.
The sled door closed behind her, leaving the other scientists and the guards inside.
"This way," Altia said.
She led the way through the encampment, a handful of temporary buildings and crates of supplies, until she reached the building she used as an office.
Altia plugged a memory stick into a screen and gave it to Shivia.
"It's raw text, not formatted, with gap length indicated by dashes," Altia said, "And there are still a lot of gaps."
"Very well," Shivia said.
She looked around Altia's office space and selected a comfortable chair. She shrugged off her cloak and sat with her legs crossed, the screen balanced on a knee. She swiped her finger from the bottom of the screen upwards, the motion to turn the page, then again and again. She sat for two hours, swiping backward and forward without saying a word, comparing original symbols with Altia's translations. Altia stood in front of her, forgotten.
"This is incredible," Shivia said at last.
"Yes," Altia said.
Shivia pointed at a section of the text, and Altia looked over her shoulder at the screen.
"We are remnants-The power has been taken away—-The cold sleep—They abide——-,"the tablet said.
"You think this is important?" Altia asked.
"I do," Shivia said, "That gap at the end. I'm sure you will find that those symbols are coordinates. Decoding that is your new priority."
Shivia abruptly stood up. As she was walking to the door, leaving without a word, Altia asked.
"Can I share my findings?"
"Oh no. This must remain a secret."
