Kane stood at the top of the mountain overlooking the Los Angeles valley. From this position atop the highest peak bordering LA and Ventura counties, he see observe everything. To most people, it would be nothing more than a show of lights against the darkening skies of early evening. But Kane was not most people, he was a hunter. A hunter of the undead. With many of the same powers as the undead itself, his sole purpose for existing was to hunt and destroy this creature, which tormented the humans.
His race had been created solely for that purpose by the ancient visitors, who had unleashed this plague upon the earth. Their appearance was similar enough to the emerging human race that when their own peaceful planet had suffered a series of natural disasters, which rendered it virtually uninhabitable, a small surveying party had traversed the universe looking for a suitable home for the few thousand remaining members of their once great race.
At first, the Earth had seemed the perfect solution. They had even managed to make treaties with a few of the planet's scattered civilizations; exchanging some of their advanced technologies for the right to reside among them. They were often in the feeble minds of these humans even considered gods. The survey party had even sent a message to the fleet that they had found a suitable home.
Then it began slowly. First one and then another of the small party became 'ill.' For such a peaceful race it was a devastating milady. The first sign was increasing aggression and paranoia; not only with their human hosts but one another as well. On more than one occasion an infected member would disappear to find another group of natives; spreading fear and barbaric rituals in an attempt to use the humans to fight his former friends. By the time that the other ships arrived a human century later, it was too late. All of the survey party had 'turned.'
The council of elders and scientists, which ruled the refuges, had met for months trying to discover what had caused the strange transformation. Some thought it was an illness that had no effect on humans, but infected their species with a madness that consumed once great men. Others theorized that it was the minute differences in the gases of the Earth's atmosphere, which over time and prolonged exposure altered the mental faculties of their kind. Still others believed that the foods indigenous to this planet had created nutrient deficiencies that affected the thought processes of the brain. They pointed to the taking of human blood as an attempt to 'supplement' an inadequate diet. A few even blamed the primitive mentality of the local people for igniting long since conquered emotions of greed, lust and violence. They advocated destroying not only those of their own race, who had accepted these primitive ways, but the human insects as well. After all, as superior beings, it was their race's right to survive; even if it meant exterminating others.
These enlightened beings were fearful of the spread of the disease among the precious few remaining on the ships. While they remained in orbit above the Earth, visits to the planet was severely restricted. It was the source of many legends about silver beings with large heads and black shining eyes; the suits they wore to prevent the spread of the 'disease.'
Another world was located for settlement, but the question remained what should be done of these creatures hunting and preying upon the humans? In the end, the council had given up the search for the cause and cure; instead it felt that containment was the only solution. At first, they had sent members of their own race to hunt and destroy the powerful creatures; only for them too to turn in the end despite all the precautions.
