psicrystal

Natural mineral formations from the Quivering Caves of Proxtel, psicrystals are natural telepathic amplifiers. This came as quite a surprise to the Proxtelians, who have no psionic abilities and used the crystals as glittering vermilion street lamps. Since the crystals' special property was discovered, nighttime crime rates in Proxtelian cities have more than quadrupled under the cover of darkness.
