The Radiants moved throughout the young universe, and plumbed the diverse strangenesses within it. The beings burned as bright as their cores with curiosity, all on behalf of They Who Pass.
There was much to learn, and vast room for such a broad education. The sentient clouds of plasma swam within vast seas of glowing gas and lanes of sparkling dust, ever seeking, and felt the electrical equivalent of awe.
All they learned, they reported to their creators on the other side of the cosmic string.
But some parts of that fresh reality were beyond the abilities of the Radiants to explore. The world of cold matter defeated the ever-curious plasma beings. The very touch of dark solids greedily drained away the heart-fire of the incandescent gas clouds. The Radiants were forced to ignore their innate programmed curiosity for a time, and avoid the enigmatic points of darkness that swung around stellar fires.
There was still much to learn, and an entire new universe as lecture hall.
To They Who Pass, this new universe made little sense. It seemed paradoxically composed of two extremes: the very hot and the very cold. The Radiants could easily explore the former conditions on behalf of their masters, but the bitter chill remained quite deadly. They Who Pass grew intrigued at these newest findings from the other universe, and sent fresh instructions through the cosmic string window to their Radiant servants. This still-stranger frontier of cold must be explored as well.
Under careful instruction, the Radiants recapitulated the original act of their own genesis. They used the interactive properties inherent to matter far colder than their own diffuse blaze. Instead of patterns implicit in the dance of atoms stripped bare of electron clouds, subtle and little-known forces pushing and pulling at atoms were investigated.
Tests began. Cool gas clouds were visited and influenced at a distance by the Radiants. The beings of plasma reached out with tools of collective force into the dusky strangeness. Linear chains of atoms met and branched, joined, and were torn asunder with careful prodding. Complexity grew, as did the knowledge of the Radiants.
They Who Passed marveled in their distant way at such knowledge, and urged their servants to continue the investigation. Regardless of the medium used, Mind was formed from Pattern. Perhaps even this killing blackness could give birth to Mind, and thus fresh servants, in yet another mode of existence.
Much was discovered about condensed matter. It was blunt, willful, incapable of vibrating with the singing energies that were the lifeblood of the Radiants. But diffuse clouds of dust were not enough. With great care, the Radiants learned to come near the cold deadly spheres of matter, and study their composition by deft inductance. Patterns were imposed by the Radiants into slow currents of superconductive liquids, found in pools on the cold lumps of matter. There, as in the plasma clouds of the Radiants' birth, impurities lent a non-homogeneous nature to the medium: raw material for the primitive minds even then forming structures within the liquid.
As electromagnetic forces were not sufficient to touch and move cold matter, a skin of protective polymer was fashioned over the superconductive liquid. Flexible struts of crystalline material gave shape and strength under the brute, inexorable pull of gravity.
After a time, a bulbous entity heaved itself out of a pool of liquid helium. It slowly extruded a strand of matter from its center. The tentacle slid along the cold surface, and finally wrapped around a small rock.
Slowly, the dimly thinking coldlife automaton lifted the rock against the light gravity. It waved the prize toward the glittering plasmid cloud orbiting the cold planetoid. The tentacled construct felt something like a frigid triumph, and quested around for new objects to investigate.
Thus were the Dark Ones born.
For many revolutions of the galaxy, the Dark Ones carried out the bidding of the Radiants in the world of cold matter. The Radiants themselves continued their explorations at the other end of the spectrum, basking in heat and light unimaginable. Together, the two classes of Mind explored the new universe, finding things awesome and strange.
The Dark Ones moved from cold rock to still colder, tasting and examining. Learning. Yet it was not sufficient, as they could sense other worlds in space around them. They learned to build self-contained nests to carry expeditions across great distances in search of knowledge. Such was the curiosity of the Dark Ones that some nests could travel faster than a photon in vacuum.
The Radiants in turn fashioned large structures of gas, dust, and electromagnetic fields. The tenuous constructs were designed to listen to the faint songs of other galaxies, or the brittle noises from the surfaces of neutron stars. Mysteries worth investigating abounded at the fiery centers and great whorls of galaxies.
Much was learned about the new universe by the Dark Ones and the Radiants. That information was carried by the glowing plasma clouds to one of the still wriggling cracks in time and space. The messenger Radiant, bloated with information, would intercalate into the very field lines of the cosmic string, an intimate touch of blended attraction and repulsion. Stretched thin, the intelligent cloud would wrap tightly around the portal between universes, and send the collected information to They Who Pass, dwelling on the other side of the cosmic string. In return, new information and instruction would be transmitted from They Who Pass into the Radiant messenger. The messenger, in turn, would free itself from the cosmic string and spread the new tidings.
So the situation remained for many eons. Until the Conundrum.
They Who Pass ceased to speak to the Radiants through the tortured windows of their cosmic strings. The children they had sired in the new, strange universe were left to their own devices. To find their own destinies without the influence of their creators, fallen silent on the other side of an interdimensional crack between realities.
The strange children of They Who Pass had drive, but no longer purpose. Their drive became their purpose.
The Radiants soon became uninterested in the Dark Ones, focusing instead on issues far from the solid phase of matter. Some Radiants learned how to transform themselves into less delicate forms, able to withstand existence within the cores of suns. Vast communities of the plasma beings lived in the turbulent core of the galaxy, seeking the unknowable. Others remained wrapped and intertwined within the massive lines of force surrounding the now silent cosmic strings, plaintive, hoping for the return of They Who Pass.
After a time the Radiants seldom communicated with their cold servants, made of dull matter instead of lively plasma. The sentient clouds fell as silent as their creators on the other side of the cosmic string.
They had other concerns.
The Dark Ones, too, were forced to find their own destiny in the cosmos. Many of them simply traveled without end, continuing to observe and store data as they had before – even without a recipient to which they could deliver.
Others made a ritual and religion of following precisely the ways of the Old Time, when Radiant and Dark One and They Who Pass were in constant communication – perhaps the Great Silence was due to a lack of following instructions with strictest accuracy. A few Dark Ones developed their own interests among the other, native minds that eventually dwelled in the new universe. These less organized Dark Ones found that their ancient drive to collect information could be useful, and that it was possible to manipulate these new upstart sources of data to acquire still more.
The majority of the Dark Ones – regardless of social structure – would have nothing to do with other, lesser minds which developed in the new universe. They preferred to brood in a silence to match that of They Who Pass.
Those Dark Ones who did upon occasion interact with the new sentients came to be known by many names throughout the galaxies, a name pronounced by a dizzying variety of communication organs.
In one area of space-time, the various inhabitants called them the Outsiders.
