A particle that is used to carry a pre-programmed signal.
Reportions have been in existence since the beginning of communication. When an electron sends a photon to another, a reportion is traveling right along it in the subspace and superspace equivalents. When a human speaks to another human, there is a veritable shower of reportion movement. When galaxies merge and mix their histories, the reportion movement energy is on par with that of an exothermatic nuclear bomb.
During the 2063 Solar-Centauran war, the Centaurans used reportion beams to destroy the Solar Fleet's Fictionium starships.
