controlled pattern. The energy release caused the ship to be instantaneously transported along the foldline
to the system of Luyten's Star, some 12.5 light-years distant from Sol.
There was no holding the human race back after that. Over the next several centuries, the leakage of
population into space became a flood. The pattern of the migration was determined almost entirely by the
shape of foldspace, as the aggregate of foldlines and foldpoints came to be called. While some stars
were found to possess only a single foldpoint, others were endowed with two, three, or more. The
biggest, most massive stars were found to be especially fertile centers of foldpoint production; and
therefore, the systems of these stars became the crossroads of interstellar travel. The red-orange
supergiant star Antares was the champion foldpoint producer throughout human space. Its six interstellar
portals made Antares the linchpin of a network of related star systems known collectively as the Antares
Foldspace Cluster.
When Antares exploded on 3 August 2512, the immediate effects were felt far beyond the confines of
the Antares system. The release of so concentrated a burst of energy jolted the very fabric of space-time;
and with it, the structure of foldspace for hundreds of light-years in every direction. In some systems,
foldpoints underwent radical changes of position, while in others; foldpoints appeared where none had
previously existed. In still other star systems, preexisting foldpoints disappeared without a trace.
The F8 dwarf star known as Valeria had been doubly unlucky. Situated 125 light-years from Antares,
the Val system was what foldspace astronomers called a cul-de-sac, a star with but a single foldpoint.
When Antares exploded, Valeria's foldpoint had simply disappeared. Thus, it was that the human colony
on Valeria IV (Alta to its inhabitants) had found itself isolated from the rest of human space for a century
and a quarter. Then, early in the year 2637 (Universal Calendar), Antares had burned bright in the Altan
sky, signaling the arrival of the leading edge of the nova shockwave. Simultaneous with the passage of the
nova shockwave, Valeria's foldpoint had reappeared high in the system's northern hemisphere.

"What's this?" Drake asked Bethany, gesturing toward the display.
"Part of the government's 'Know Thy Enemy' campaign," she replied. "They've got them in most public
places. Push the button and it will spew out all manner of interesting facts. Here, listen.” As she spoke,
she stepped forward and pressed a stud that jutted from the base of the holocube. The image came to life
and seemed to peer down at them. At the same time, a sonorous voice began to speak.
"The creature you see before you, sir or madam, is a Ryall, and the mortal enemy of all humanity..."
The image in the holocube was that of a creature designed along the lines of a six-legged centaur. The
legs were short, less than half-a-meter in length, and culminated in wide pad like feet. Their shortness was
amply compensated for by the creature's forebody – a vertical torso topped by a long, flexible neck that
carried the alien's head to the height of a man's. The head was wide at the back, showing considerable
cranial bulge, and narrow at the front where a toothy snout jutted forward some fifteen centimeters. The
eyes were set wide apart, such that the creature had trouble looking straight ahead. In the hologram, its
head was cocked to one side, as though scanning the faces of passersby. The mouth was partially open,
showing two rows of conical teeth and a triply forked tongue. On top of the head were two flaps of skin
stretched taut by rigid, spike like projections. Of nostrils or any equivalent, there was no sign.
Two heavily muscled arms attached to the forebody at the same point as the neck. The creature's hands
consisted of four slender fingers flanked by two opposable thumbs. At the opposite end of the main
body, a meter-long tail dragged the ground. The Ryall's hide was scaled, the scales shading from
gray-green on top to light beige beneath.
