Chroniton Chronitons are subatomic particle s with temporal properties . Although not harmful to humanoid s , chronitons can be fatal to lifeforms which exist outside of time , such as the beings known to the Bajoran s as " Prophet s , " and their mortal enemies , the Pah - wraith s . ( ) Chronitons were produced by the normal operation of Romulan cloaking device s , and were often associated with the phenomenon of time travel . The Orb of Time was known to produce a surge of chronitons when in operation . The temporal transporter utilized by the crew of the 29th century timeship " Relativity " produced a detectable chroniton flux of . 003 . ( ; ; ) The Borg utilized chroniton fields , projected throughout a Borg vessel via specially - designed conduits , to compensate for the extreme temporal stress of a transwarp conduit . ( ) Overview . In 2368 , Lieutenant Commander Geordi La Forge and Ensign Ro Laren became " phased " due to exposure to chroniton particles being emitted from the cloaking device of a Romulan science vessel which the " Enterprise " was assisting . As the Romulans had attempted to produce an interphase generator by combining their cloaking device with a molecular phase inverter , this had the effect of altering La Forge and Ro ' s molecular structure , making it impossible for them to interact with anything but each other . ( ) In 2371 , the chronitons produced by the ' s cloaking device , which had lodged in the ship ' s ablative armor matrix , shifted into a high state of temporal polarization due to a temporal surge from an exploding microscopic singularity passing through the Sol system . This caused a transporter beam passing through the polarized particles carrying Captain Benjamin Sisko , Lieutenant Jadzia Dax , and Doctor Julian Bashir , to be redirected through time , resulting in their materializing in San Francisco , the year 2024 . Chief O ' Brien and Major Kira were later able to use the remaining polarized chronitons to mount a rescue mission for their stranded crewmates . ( ) In 2373 , a Pah - wraith inhabiting Chief O ' Brien ' s wife Keiko forced Miles to perform a series of modifications to Deep Space 9 ' s deflector grid , transforming the station into a massive chroniton array aimed directly at the Bajoran wormhole , where the temporal disruption would kill all of the Prophets . O ' Brien was able to successfully complete the modifications , but instead of aiming the chroniton beam at the wormhole , he targeted the runabout which he and Keiko were aboard , driving the Pah - wraith out of Keiko ' s body . A year later , Kai Winn utilized a chroniton generator to drive out a Prophet and a Pah - Wraith who had inhabited the bodies of Major Kira and Jake Sisko , respectively . Although Captain Sisko insisted that the battle between the two , called " the Reckoning " in Bajoran mythology , be allowed to play out , Winn covertly activated the generator in an attempt to subvert Captain Sisko ' s role in Bajoran affairs . ( ) The Delta Quadrant species the Krenim utilized chroniton - based torpedoes as weapons , which had the ability to pass through an enemy ' s shields due to being in a constant state of temporal flux . In at least one version of 2374 , Kes was exposed to chroniton radiation from a torpedo fragment . Although she was inoculated against the radiation poisoning , five years later the dormant chronitons in her s would be reactivated by exposure to a biotemporal field . This shifted her cells into a state of biotemporal flux , causing her to experience a series of backward time jumps , essentially living her life in reverse . The time jumps were halted in 2373 when The Doctor was able to expose her to a precisely modulated field of antichroniton s , purging her system of the chronitons . ( ) In 2374 , when Molly O ' Brien fell through a time portal on the Bajoran colony world of Golana , Lieutenant Commander Dax and Molly ' s father , Miles O ' Brien , were able to determine that Molly had been sent approximately three hundred years into the past by analyzing the chroniton signature . ( ) In 2377 , " Voyager " encountered a spatial rift emitting high levels of neutrino s and chronitons . When a chronokinetic surge struck the ship , it was fractured into thirty - seven different time periods . The Doctor of two years into " Voyager " s journey subsequently created a chroniton - infused serum to treat Commander Chakotay of the time period when the accident had occurred , whose body was in a state of temporal flux as a result of the surge . The serum allowed Chakotay to pass through the barriers separating the time periods , and recruit Captain Janeway ' s counterpart from 2371 , injecting her with the same serum . Chakotay and Janeway then started distributing the serum throughout the ship , using the bio - neural circuitry , and then used the gel pack s to transmit a chroniton field , generated by " Voyager " s warp core , based on a plan devised by Seven of Nine . The plan was successful , and " Voyager " was brought back into temporal sync to a time period mere moments before the chronokinetic surge struck the ship . With only seconds , Chakotay rerouted power to the main deflector and reset its polarity , using it as a lightning rod to absorb the surge , averting the accident . ( )
