During elision, a subject would converse and react in a manner not unlike his or her normal behavior patterns, but, occasionally, would perform horrible, sociopathic acts without seeming to notice anything unusual. After the elision was complete, the subject would have no memory of the attack--all memory of it, and even the idea that such memories were missing, having been "elided."
Given the subjective and self-concealed nature of the elision experience, it is impossible to know when it first manifested on a galactic scale. It is known that [Sable Aliss]? was the first to notice and track its effects; it was also she who used her resources within the nascent Klein Brittan group to prove that elision was reproducible, as a side effect of the subspace harmonics generated by the prototype Void-Breaker?s. It was Alexander Ducant, however, who registered and publicized the changes in neuroelectric activity that occur during elision, and which can be detected for days after an attack.
Given the manner in which the Aliss's Dysgnostics attempted to exploit the elision effect, it's not surprising that most attempts at destroying Ducant's scholarly name are traced to them. Neither they nor he ever answered some nagging questions, however. Since Aliss was able to document elision before the first military Void-Breaker? was constructed, there must have been another source; but if it was not a Void-Breaker, then what was it? And if it was, what or who had the ability to use them before the [Qirel Encounter]??
