Avaajeen

Avaajeen is a fictional mineral and concept used in speculative fiction and worldbuilding. It is not a real element or ore. In many narratives, avaajeen is depicted as a luminescent, energy-dense mineral found in asteroid belts and the crusts of small moons, sometimes embedded in crystalline veins. Its crystals glow and shift color in response to radiation, and it is valued for its high energy density and potential for advanced technology.

In common depictions, avaajeen powers reactors, fuel cells, or propulsion systems and serves as a central economic driver due to its scarcity. Processing ranges from straightforward refinement to demanding purification steps, depending on the author’s world.

The term appears across novels, tabletop games, and video games as a tool for worldbuilding. Because the concept has no single canonical origin, names, properties, and uses vary between works. It is sometimes associated with ancient civilizations, hidden vaults, or political conflict over mining rights and trade routes.

In usage, avaajeen is often a plot lever: control of deposits can determine power dynamics, and expeditions to distant worlds to harvest it drive exploration narratives.
