Icaron

Icarons were artificially created tachyon particles found in hyperspace. Icarons were named after Icarus.

They were useful in constructing hyperspace-capable vessels, as Icarons 'preferred' to be in hyperspace; there was a much smaller energy demand placed on a ship when it entered hyperspace and no energy to remain there.

Most societies banned the development of Icarons because they caused paranoia and psychotic behavior in carbon-based lifeforms. Individuals who underwent a body bepple were particularly at risk. (PROSE: Original Sin)
