The Vault

The Vault was a location within the Romulan Star Empire.

This highly classified location was in fact a cloaked military facility with the only means of entry being a encrypted code that was known to members of the Imperial Romulan Senate and the Romulan High Command. The base served as a hidden research facility where certain technology's were studied and also served as a safe haven for the ruling council in the event of a threat to the homeworld. In addition it was to serve as a rendevous point for the remnants of the Romulan Star Navy.

In 2387, Romulan miner Nero learnt of the location of the Vault after assassinating the Praetor and members of the Senate. Travelling to it, he claimed that he was given the codes by the Praetor before his death. Once at the facility, he met Commander D'Spal who revealed to Nero that Borg technology was being studied at the facility and refitted the Narada with it in a plot of vengeance against the United Federation of Planets.
