Star Trek: The Lost Era is a book series that chronicles the events occurring between James T. Kirk's presumed death aboard the USS Enterprise-B in 2293 and the Cardassian withdrawal from Bajor in 2369. The series attempts to flesh out some events that were only mentioned briefly in the TV series, such as the Tomed Incident and the Betreka Nebula Incident. It also helps to provide a backstory to recurring book characters such as Leonard James Akaar, Elias Vaughn, and Dr. Selar.
