Incandescence

When this segment was completed and moved into position, an array of precision accelerometers measuring the phase difference between counter-rotating superconducting currents would track its orientation, and a faint breath of ions from its attitude thrusters would keep it perfectly aligned. The insect-eyed instrument package that sat at the telescope's focus was already complete, and undergoing testing and calibration. Once a million or so of the ten billion segments were in place, some worthwhile data collection could take place, albeit far more slowly than it would when the full light-collecting area was brought into play. At that point, the telescope would be imaging the accretion disks of thousands of neutron stars simultaneously, hunting for the telltale spectrum of an Ark's synthetic walls.

Probes had scoured the rubble-strewn center of the sole Ark that remained in this system, but had found neither artefacts nor the mummified remains of its original inhabitants. Though the higher tiers of the wind-fed ecosystem had probably collapsed quite quickly, there was a sufficient population of microbes even now to make short work of anything organic, and the slow grinding of the rubble over the millennia had milled any remnants of the inhabitants' material culture down to dust. Rakesh didn't dare to guess what the chances were that any of the Arks captured by the neutron star had thrived — even briefly, let alone for fifty million years — but he had written off the cousins prematurely before, and he was not about to make the same mistake again.

He turned away from the mirror and let his avatar drift, spinning slowly. He shifted his vision down the spectrum, into the infrared and microwave bands, dimming the fierce stars but revealing the eerie world of gas and dust in which they were embedded, full of structures more subtle, delicate and diffuse. Shells of plasma from thousand-year-old supernovas hung in space like the smoke from some slow-motion fireworks display. Half a dozen glowing filaments lined up perpendicular to the galactic plane shone with the synchrotron radiation of electrons spiraling along magnetic field lines. From a ring of gas a dozen light years wide that circled the galactic center, a surreal double helix stretched across the sky: the infrared glow of dust trapped by a wave in the magnetic field that was anchored to, and twisted by, the orbiting gas.

Somehow, the Aloof had mastered this beautiful, perilous place and claimed it as their own. While Rakesh's hapless cousins had been hammered relentlessly by the forces of nature, perhaps to the point of extinction, the Aloof had overcome or circumvented the same hardships, to make this their jealously guarded home. Whether they'd matured in the disk first and only come here once they were armed with sophisticated technology, or whether their whole mode of existence had rendered them impervious to the dangers of the bulge from the start, was anybody's guess. Rakesh did not expect answers from them, at least not directly, but he couldn't entirely surrender the naive hope that merely being allowed inside the fence and permitted to see what the Aloof had seen, to steep his body in the same radiation and feel the same stellar winds and tides, might yet crystallize some insight about their nature that could never have formed from idle speculation back in the disk.

Parantham spoke, puncturing his reverie.

"We have company."

This assertion was so bizarre and unexpected that Rakesh simply floated in silence for a while, refusing to abandon his sanctuary among the spiders to see if she was joking.

"What do you mean?" he finally replied.

"Someone has sent us a messenger. I've already asked it what it wishes to say, but it insists on speaking to us together."

Rakesh took his senses out of the avatar, back to his body slumped in a couch in the control room of Lahl's Promise.

Standing beside Parantham was a figure resembling Csi, as Rakesh had perceived him back in the node: the same bald head, the same serious demeanor, the same barely visible hint of a smile. Unlike Csi himself, it was meaningless to ask what this messenger really looked like; as an insentient courier it had no self-perception, let alone any need for a physical embodiment. Their hosts had simply loaded it into one of the habitat's processors and let it communicate with them via Amalgam-standard protocols.
