Hologram Speak

Language spoken by many groups of To'rer'ot that involves making use of their body hologram.
In modern times this is primarily used for long range, high speed communication where shouting words is not loud enough to be heard. Some languages use the hologram to project various written characters of the respective language writing, but this process can take a long time. Some languages use something similar to morse code. Others use it to project images of what the person is talking about.
This form of communication can be intercepted however, by potentially unwanted parties. Verbal communication can be too, but this is visible from longer distances. It can also reveal one's location, which, during a war, can potentially get them killed if not used carefully. Not all to'rer'ot know the language though, but due to its utility most military personnel are encouraged to learn it. However in more modern times the Sulethis Republic has made efforts to unify all the projector languages so now there are about 10.
