Shadowlings, also sometimes called Nightflyers are living pockets of darkness are occasionally summoned by Cultists and can be used only to commit murder. Shadowlings are almost mindless and crave living flesh to survive. They can be controlled only through the use of appropriate rituals and even then they can only be directed to attack a specific target, to flee, or to crawl in a containment box. Losing control is usually fatal. The Shadowling will attack its summoner on sight.
Shadowlings cannot survive in the open for more than a few hours at a time, and then only at night. Exposure to sunlight is almost immediately fatal. The creature suffers D6 x 10(30) points of damage every Turn it is standing in the open during a sunny day. Being indoors or outside on a cloudy day reduces the damage to D10 points. At night, the Life Point loss is a mere 5 points per hour. Only if the creature is kept in a metal box (made of some heavy element, like lead or gold) can it endure its existence on Earth without suffering damage.
When released Shadowlings are brutally lethal opponents. They scurry at amazing speed (Speed 25), are immune to most damage, and cause horrific wounds with the merest touch.
