Lirnas
Lirnas is a fictional mineral described in science fiction literature and role-playing games. It is depicted as forming in ultra-high-pressure pockets within planetary crusts and in meteorite impacts, where it crystallizes as pale violet prisms with a subtle glow. The term lirnas is derived in-universe from the Lirna language, where lir means light and nas denotes a substance.
Physical properties vary by author, but common features include high energy density and luminescence under ultraviolet
Occurrence and mining: It occurs in limited quantities, often in isolated pockets near tectonic faults or meteorite
Applications and significance: Because lirnas stores energy densely and has stable emissions, it features in propulsion
