Phyrric Gasses

Pyrric gasses are native to the Empyrean Viscera. While extraction is difficult, costly, and sometimes even deadly, the payoff is a fuel which can readily burn for years at very high octane. Many light-based weapons and spacecrafts use Pyre; refined pyrrhic gas.

Currently the Deep Wars are fought over Pyrrhic. The belief that whoever owns the greatest supply of Pyrrhic will usher in a new Golden Age is widespread.
