- Starbase 234 was formerly located in Nimbus sector in Tau Dewa sector block in Star Trek Online, but this was changed to H'atoria sector when Cryptic Studios redesigned interstellar space in 2015.
By early 2368, the starbase was commanded by Fleet Admiral Taela Shanthi. At this time, the USS Enterprise-D traveled to the starbase following the outbreak of the Klingon Civil War. After a meeting with Shanthi, Captain Jean-Luc Picard gained permission to take a task force and blockade the Klingon-Romulan border. (TNG episode: "Redemption, Part II")
A few months later, the Enterprise-D was recalled to the base by Fleet Admiral Ruah Brackett. Once the Enterprise arrived, Brackett informed Picard of Ambassador Spock's disappearance and his later discovery on Romulus. (TNG novelization: Unification)
By 2381, the Starbase was under the command of Admiral Owen Paris. Admiral Paris had only been in command for four months before the invasion of the Borg Collective that year when Starbase 234 was one of five simultaneous attacks along with bases 157 and 343 and the planets of Khitomer and Korvat. Starbase 234 was destroyed, but managed to destroy the Borg cube with it. (ST - Destiny novel: Gods of Night)
In 2409 the starbase added additional personnel to handle the expected increase in traffic due to the founding of the colony on New Romulus. Starfleet staged military exercises outside culminating in a simulated attack on the station itself, while the Klingon Defense Force launched at least one hit-and-run raid. (STO mission: "Starbase 234 Patrol")
In 2410, the starbase was attacked by Herald forces during the Iconian War. This was due to the fact that Starbase 234 was the only thing between the Heralds and their main target, New Romulus. All civilians and most personnel were evacuated, but the station was lost. (STO video game: Blood of Ancients)
