- "Season 5 Dev Blog #6": On Stardate 86963.65 (Dec. 18, 2409), Admiral Sola recorded in her captain's log the mystery of the derelict Jem'Hadar Attack Ships found by U.S.S. Belfast. She has her first officer try to contact the Dominion, without success, and orders the Corps of Engineers to study the vessels.
- "Season 5 Dev Blog #22": Lieutenant Commander C'thal records in her Personal log that her SCE team has completed the analysis. The "ghost fleet" is 35 years old and dates back to the Dominion War. neutrino pulses are the key to the mystery. C'thal reports that Belfast's science officer, Lt. Commander Tem Inasi, rules out a connection to null space. C'thal's research eventually points to the Bajoran wormhole and the Jem'Hadar fleet that disappeared in 2374.
