Iagreous
From Rise: The Vieneo Province
Iagreous is the fuel of the modern world. Its refining and production has allowed the exploration of space.

Fuel Ore
In its raw form is a diamond hard crystalline substance synthetically created and formed into large, transportable blocks. These blocks are taken to docks and bases, and broken down through nuclear means to create an energy-rich gas known as Iagreous. Iagreous gas is then sold to ships, docks, and all other Iagreous-based reaction systems.
Refined Fuel
In its gaseous state, it is a highly-energized plasma which, by the nature of plasma, can be elecromagnetically contained and distributed. It can be used to generate electricity (induction) and propulsion (either by releasing the compressed plasma directly or driving an axial turbine).
