But the true value of the para-resonating talent had soon become evident. Now, two hundred years after the energy Curtain had closed, isolating the colonies, amber was the chief source of energy. It was used to power everything from washing machines to computers.

For most people, the ability to generate and direct currents of psychic energy was a low-level, generalized talent. There were those, however, who exhibited much higher levels of para-resonating ability. In such cases the talent always took a highly specialized form and was directly linked to objects and artifacts left behind by the first colonists on Harmony, the long-vanished alien empire. All of the relics of the lost civilization radiated heavy psi energy.

The aliens had disappeared eons before the arrival of the settlers from Earth, but they had left behind a vast network of catacombs that crisscrossed the planet beneath its surface. Recently a massive underground rain forest had also been discovered. Like the tunnels, the jungle was filled with strong currents of psi. Some of it took dangerous forms. That was where ghost hunters came in.

Hunters were prime examples of para-resonators with strong but extremely limited talents. Their psychic abilities, while admittedly impressive, were not exactly multifunctional skill sets. As far as anyone had been able to discover, the only use for a hunter's talent was to manipulate and control the highly volatile, potentially lethal balls of fiery, acid-green alien energy known technically as unstable dissonance energy manifestations—UDEMs.

Everyone called the miniature storms ghosts, because they seemed to drift like lost specters through the underground world, creating major hazards for those who ventured beneath the surface.

Getting singed by a ghost was no small disaster. A close encounter with the wild energy fields could destroy a person's psychic senses. It could also put the unlucky victim into a coma from which he might never recover. The only people who could control the ghosts were those who could resonate with the chaotic dissonance energy that fueled them: ghost hunters.
