Archive vault
Alternate reality
Spock archiving the Abronath in the archive vault
The archive vault was a location aboard the USS Enterprise in the alternate reality.
In 2263 – three years into a five-year mission the starship was undertaking – the archive vault aboard the Enterprise housed a piece of the Abronath, placed there after the Teenaxi refused to accept it as a diplomatic offering from the Fibonan High Council.
Using his remote connection to the Federation database and Starfleet logs through a Magellan probe, Krall was able to detect the Abronath aboard the Enterprise. Its discovery initiated his attack on the Federation from the planet Altamid, beginning with the destruction of the Enterprise and the recovery of the artifact. (Star Trek Beyond)
