Vault K-23 was the Galactic Republic designation for a Rakatan vault located in the northeastern corner of the Varactyl Vale, an area of the Minimum Security Section of the Republic's Belsavis prison on the planet Belsavis. During the invasion of Belsavis during the Galactic War, Havoc Squad rendezvoused with Dagger Wing in Vault K-23 after recovering medical supplies for the wing's injured pilots, and repelled an Imperial incursion into the vault.
