2369
Investigation of the Bajoran Wormhole. 
 * "First Officer's Log, Stardate 46392.7. We are preparing to launch a rescue mission to find Commander Sisko. But first our navigational sensors must be recalibrated to work under the conditions reported by Lieutenant Dax."


 * "First Officer's Log, supplemental. We've rendezvoused with the space station at the former co-ordinates of the wormhole. Unfortunately, our scans have revealed no trace of either the wormhole, or Dukat's ship. A few minutes ago, three Cardassian warships crossed the border, no doubt on their way to search for Dukat."

2371
Mission to Earth. 
 * "First Officer's Log, supplemental. Somehow Sisko, Dax, and Bashir have altered Earth's history. We have no choice but to send an away team into the past to try to find them and correct the changes to the timeline. The only problem is, we're not exactly sure where to look, or when."


 * "First Officer's Log, supplemental. Upon returning to the present with our missing crewmembers, we were relieved to discover that the timeline had been restored."

Mission to Prophet's Landing. 
 * "First Officer's Log, Stardate 48521.5. Odo and I are returning to Deep Space 9 after reviewing security procedures at Prophet's Landing, the Bajoran colony closest to the Cardassian border."
