“Excuse me if I interrupt your thoughts, but do you wish to see the next sequence?” Kallik was standing by her side. Darya had no idea how long she had been waiting there.
She shook her head. Since her findings made no sense, additional data were more likely to confuse than to clarify.
Darya realized how tired she was. How long since she had slept? How long since they had entered Labyrinth, how long since they arrived in this chamber? She couldn’t even guess.
Still there was no sign of J’merlia. She and Kallik should have gone searching long since. The fascination of the polyglyphs had held her.
The worst of it was, she wouldn’t be able to sleep now no matter how she tried. And it was not because of worry over J’merlia. Darya knew her own weaknesses. She might close her eyes, but the image sequences were going to keep running, running, running, visible to an inner eye that could not be closed. They would remain until something in her brain over which she had no control permitted them to vanish. Then she would rest.
“Kallik, do you mind if I talk to you?” Hymenopts, unlike mere humans, never seemed to become weary. “I’d like to share some thoughts, think out loud at you.”
“I would be honored.”
“Did you watch all three sequences with me?”
“Yes, indeed.”
“But you didn’t see Quintus Bloom’s presentation, when he was on Sentinel Gate?”
“That was not my good fortune.”
“Pity. Did you, by any chance, examine the recording of the presentation in Bloom’s data files on the Myosotis?”
It occurred to Darya that for someone who had asked to share her thoughts, she was doing rather poorly. So far everything had been a question. But Kallik did not object.
“I examined the records on the Myosotis, and I found them fascinating.”
“Good. So you saw what Bloom says he found in Labyrinth, and we’ve both seen what we found here.”
“Some of what we found here. With respect, three image sequences remain to be displayed.”
“That’s all right. We’ll get to them. We need to think, frame a hypothesis, then use the other image sequences to test it.”
“That is a procedure fully consistent with the scientific method.”
“Let’s try to keep it that way. First, Bloom’s image sequence. It was consistent with our past, and what we know of the past of the other clades. It showed a future with all clades present, and it showed a spiral arm full of colonized worlds. Now for a question: Was that the only image sequence that Bloom found?”
“We lack the data to provide an answer.” Kallik stared all around her with her rings of eyes. “However, we do know that Quintus Bloom came to a hexagonal chamber like this one, even if it was in a different interior.”
“Which is very probable. But you mean, he must have wondered what was on the other five walls, wherever he was? I agree. He seems a thorough research worker. He must have examined all six walls. But now let’s talk about what we found. Three different histories of spiral arm colonization. The past in two of them was plausible, but in every case the far future was different. Agreed?”
“Certainly. Different from each other, and also different from what Quintus Bloom reported.”
“Good. Now I’ve got my own ideas, so I don’t want to lead you on this. What do you see as the single biggest difference between what Bloom reported, and what we have been finding?”
Kallik’s exoskeleton did not permit her to frown, but her perplexity showed in the delay before she responded. “With respect, I see two major differences.”
That remark was not one that Darya had been expecting. “Two differences?”
“Yes indeed. First, we find that the spiral arm in the far future is empty. There are no populated and colonized worlds. Quintus Bloom found the opposite, an arm where some clade occupied every world.”
“That’s the difference that hit me. So what’s the other one?”
“The image sequence displayed by Quintus Bloom showed Builder artifacts. The sequences that we have seen so far offer no evidence of such artifacts. In fact, they show no sign whatsoever of the existence of the Builders, now or in the past. But this” — Kallik waved a jointed forelimb around her — “is certainly a Builder artifact. It is proof that the Builders, whether or not they exist today, certainly existed at one time.” Kallik stared unhappily at Darya. “With respect, Professor Lang. It appears to me that our very presence here, in an artifact, proves that Quintus Bloom’s claim must be correct. Only a spiral arm containing artifacts can be the real spiral arm.”
During her scientific career, Darya had developed immense respect for experimental data. One little fact was enough to destroy any theory ever constructed, no matter how beautiful and appealing it might seem.
Now she was facing one ugly and very big fact: Builder artifacts appeared in Bloom’s images, as Kallik had pointed out, but not in the ones that they had seen. There was no way of arguing around that, no way of dismissing it as irrelevant or unimportant.
The smart action at this point was also the simple one: accept that Quintus Bloom’s images represented reality, while the new ones, whatever they might be, did not. With that full acceptance, Darya would at last be able to relax and get some sleep.
She might have to do that — but not quite yet. One of her ancestors must have passed along to her a good slug of stubbornness. She was almost ready to quit, but first she had to see the other three image sequences.
Kallik, at her direction, patiently prepared to run them. During the setup period, Darya’s tired brain took off on a new line of thought.
Labyrinth was a new artifact. On that, she and Quintus Bloom agreed one hundred percent. Not only did it look new, with none of the long-deserted appearance of every other artifact that Darya had ever encountered, it was also too close to the populated planet of Jerome’s World to have escaped detection through thousands of years of exploration and observation.
There was more. Not only was Labyrinth new, it was not in any way hidden. Whoever built it, intended it to be found. Darya felt sure of that, although her thinking was now far indeed from the testable, provable world of hard evidence.
Don’t stop yet. If Labyrinth were found, it would also be explored. The designers of Labyrinth expected that at some time, an intelligent being — human or alien — would reach this very chamber. Someone would stand here, as Darya was standing, and stare at the milky, streaky walls. They would puzzle over their meaning and significance. Once you accepted that such discovery and exploration were inevitable, then the idea that the sequences Darya and Kallik had seen so far were no more than Builder fantasies became ridiculous. The three sets of images — the spiral arm past, present, and future — were solid, important data, as real and meaningful as what Bloom had discovered. Whoever found the inner chamber of Labyrinth was supposed to deduce what it all meant.
And then do what?
That was the point where Darya’s thinking stuck. She was supposed to stand just where she was, and conclude — what? It was like some sort of super-intelligence test, but one that she was failing.
She sighed, and came back to reality. Kallik had been ready long ago, patiently waiting.
“All right.” Darya nodded. “Let’s see what we’ve got in the other three.”
At first it seemed nothing but more mystery and disappointment. The fourth sequence showed a very simple progression. The green clade, the one that Darya had never managed to identify, arose far away in the spiral arm. The green tide spread, sun after sun, until the arm was ablaze with green. No other clade ever appeared. At a time not long after the present, the green points of light began to pop out of existence. Finally all were gone, and the spiral arm remained empty to the end of the display. No Zardalu, no humans, no Cecropians. And never a sign of the bright magenta that had marked the Builder artifacts in Bloom’s display.
