Under certain types of magnetic stress, Black Ballybran, for lack of any better description, absorbs all light and seems to become

black. Milekey had observed this phenomenon when he chipped the first lump from the black crystal face.
Again by accident, while being examined by the crystalographers, the substance’s true properties were discovered. If two identical segments of black quartz were subjected to synchronized magnetic induction, a two-way communication link was established between the crystal segments. When investigators increased the distance between the samples, it was discovered that, unlike other electromagnetic phenomena, black quartz eliminated the time lag.
Concurrent with the laboratory discoveries and proposed applications of the new crystals came the first of several problems to be solved in the mining of this rich source. The first E and E team had only gathered up loose chips of the various types of crystal, or such larger chunks as had already been fractured from the mother lode. In attempts to cut with ordinary carbon-10 blades, the crystal had shattered. Laser cutters were tried, but they shattered, melted, or damaged the crystal.
The habit of one of the crystallographers of singing as he worked led to an unexpected solution. The man noticed that some crystal faces would resonate to his voice, and he suggested the use of a subsonic cutter. Though not completely successful, experiments along this line finally produced the sophisticated audio pickup that resonated, amplified, and reduced the required note to set the subsonic diamond blade.
Once the problem of wresting unblemished crystals from the face was solved, Ballybran was opened to private miners. During the next spate of storms, those miners who heeded the warnings promptly and reached the sheltered valley sustained no injury. The imprudent were discovered in the storm’s wake, dead or mad. Storm winds blowing across the resonant crystal range coaxed enough sonics from the sensitive rock to shatter unprotected minds.
Keenly aware of the unexplained deaths of the nine miners, everyone became conscious of previously ignored physical discomforts. The meditechs began filing reports of disorientation, hypo- and hyperthermic spells, erratic sense perceptions, muscular spasm and weakness. No one in the several base camps escaped the minor ailments. Most symptoms passed, but some victims found one sense or another—in most cases hearing—to be affected. The medical team was hastily augmented, and everyone was put through exhaustive tests. At first, crystal was suspected of inducing the symptoms. However, those handling the crystal off-planet appeared unharmed by contact, while meteorologists and support technicians who never touched the stuff on Ballybran, were also affected. Crystal was absolved. The planet’s ecology then became the prime target for intensive examination, and this area of investigation proved positive. The spore producing the symptoms was soon isolated, and the planet Ballybran was placed on Code 4 as a preventive measure.
Killashandra turned off the display to ponder that. Anything below Code 15 was a stern prohibition against landing. Ballybran’s spore produced complicated reactions—sometimes fatal—in the human body. Yet the culprit had been isolated, but the planet was

Evasion!
Killashandra thought, irritated. She started the display again, but the text now cited the formation of the Heptite Guild. She halted it.
What was it Andurs had said? “Only Singers leave the planet?” Obviously, the handicapped remained on Ballybran. Twenty-thousand-odd staff and technicians as opposed to Singers. Killashandra snorted. Those were better odds, actually, than the ones against achieving stellar rank in the performing arts. She rather liked that. Yes, but what happened if you weren’t one of the one-in-five? What sort of technical workers were employed?
