The Chova was a telepathic weapon, with no physical presence. It was developed by genetically engineering a telepathic race called the Hed'em'disol, then inserting the Chova into their minds. The Hed'em'disol would then telepathically project the Chova to their victims. The weapon first prompted dreams, then waking hallucinations, based upon the victims' perceived personal failures. The only known cure for the Chova was for it to infect someone who suffered from multiple personality disorder—only able to attack one personality at a time, multiple personas would overwhelm the Chova, essentially 'negating' it, this negated Chova subsequently being passed on to other infected to cure them.
