Isogen - light-bluish crystal, formed by intense pressure deep within large asteroids and moons. Used in electronic and weapon manufacturing. Only found in abundance in a few areas.
Isogen-5 is an exceedingly rare, extremely unstable variant of Isogen found only in blue bright star systems.
Crystalline Isogen-10 can form in space under the correct local conditions, typically requiring the abnormal gravitation fields that are found in unusual configurations of space-time topology like Abyssal Deadspace.
