Diaconium

Diaconium is a precious and rare mineral used to power limnal drives. It forms randomly in asteroids in the form of crystals. It has a white color, streaked with sliver; it is also soft to the touch, and has a slight warmth to it. Diaconium also has the following properties:
 * No odor.
 * Tastes faintly of lemons.
 * Is not conductive.
 * Exposure to extreme high heat does not affect the chemical structure.
 * Can be cut fairly easily with plasma torch. Interior homogeneous with exterior.
 * Exposure to sonic vibration at very high wavelength causes sample to emit visible light.
 * Exposure to water yields no interesting effects.
 * Exposure to various concentrated acids and bases yields no interesting effects
 * Exposure to high explosive yields no interesting effects.
 * Ingesting a small quantity leads to no ill effects, except a slight pain while urinating.
 * Slowly decays; small samples left alone can disappear completely if given enough time
