Freezer 7
From Tardis Wiki, the free Doctor Who reference
Freezer 7 was where Abigail's body was kept, in the cold storage of the Vault.
It was opened by director Vanessa Hardcastle when she told Giles and Archie about the girl, and much later, after an incident with Cyberon taking Abigail as its host, Abigail found herself to be alive despite the only thing keeping her to life being Cyberon, even though it had left her body at that point.
