Voice is an intelligent and apparently malicious entity. At the current time, its true nature and identity both remain unknown.
Although Voice was doubtless encountered many times by many people beforehand, the recognised first contact with the Imperial Combine took place with Elm Caden on the surface of Meccrace Prime.
Exactly what Voice is has not yet been established, but Caden and his associates have drawn various inferences from their encounters:
It has been pointed out by Caden that verbal exchanges he had with Rasas prior to Meccrace Prime may in fact have been fragments of a larger conversation with Voice.
Voice is a mysterious entity, but it does sometimes give clues to its own psychology.
On various occasions it has demonstrated indications of arrogance, self-superiority, and an almost fanatical devotion to its own beliefs. It has at times regarded human efforts to understand it with contempt and mockery.
Voice has also demonstrated great cunning and tactical insight, setting up both the Imperial Navy and intelligence bureau Eyes and Ears and leading them where it wanted them to go. On one occasion the cost to the Empire was the entire xtryllium stockpile warehoused on Ramm Stallahad, on another occasion the cost was the assassination of dozens of high-ranking intelligence operatives. And yet by nesting plans within plans, Voice has done even worse than that.
Voice sometimes indicates that it has some insecurities. It occasionally insists "I am" when conversing with humans, and often seems frustrated when it cannot make them understand this ostensibly simple assertion.
