Boronite
Boronite is an element that forms naturally in infinitesimal quantities. A sufficient amount of it could be synthesized into some of the most powerful substances in existence, such as the Omega molecule. (; )

The Borg once used a quantity of boronite ore to synthesize a single Omega molecule, but were unable to repeat the experiment as they never found another source of the ore. ()

A Vostigye space station destroyed in 2373 by astral eddies was constructed from sarium, boronite, and carbon-60 composites. ()

The Dark Matter Anomaly, discovered in 3190, was found to have removed boronite from the regions of space it passed through. This led to the hypothesis that it was mining the substance to serve as an energy source for its creators, Unknown Species 10-C. ()
