Radiant Crystals - Radiant Crystals are a naturally occurring crystalline energy source that can be activated by the aura of sentient beings. In its latent crystalline state, it remains stable enough in atmospheric conditions, whereas in its pulverized form it is highly volatile and must be stored in airtight containers for safety reasons. Weak green light flashes bounce and pulsate inside the larger crystals. These pulses offer a variety of industrial uses, including acting as a power source for machines such as airships and robots.
