The  was a facility on the ice planet Calufrax Major for storing and preserving samples of plant seeds from across the universe in case of a global cataclysmic event.

History
The Galactic Seed Vault was created by the First Gardener with the help of Time Lords. It was considered one of the most secure buildings in the universe. In particular, it had ground-to-air defences.

At some point, renegade Gardeners who preceded Nightshade by ten generations smuggled a weaponised seed into the vault. (PROSE: The Secret in Vault 13)
