TRI-LASER: The Trilithon Reaction Input laser is the basic weapon used in the 34th century. A standard laser is shined through a trilithon crystal causing a reaction in the crystal. That reaction creates the red beam of light that is fired from the gun. TRI-lasers are not that expencive to make and their light weight and compact size makes them easy to store. The double barrel lasers are twice as deadly and are more common.
