In 2370, Captain Picard's consciousness began to shift between three different alternate timelines, in different time periods, due to the influence of Q. In all three time periods he ordered an inverse tachyon pulse initiated in the Devron system, in order to examine the interior of an anti-time eruption which had appeared in all of the time periods. The pulse was emitted from the vessel's main navigational deflector. Approximately fourteen hours were required to make the necessary modifications and scan the entire Devron system aboard the USS Pasteur.
