What is the Caretaker's role?
The Warehouse Caretaker is the agent who has a form of symbiotic connection to the current incarnation of the Stable.

Their link allows them to actively search through inventory, sense if the Warehouse is in trouble, and above all be a living body for the Stable's soul to share.

A Caretaker has access to the restricted files on the current and past Warehouse secrets.

Reactivation of a closed Warehouse
Should a Stable fail to properly deactivate and later reawaken after the death of its original Caretaker, then it will attempt to form a relationship with the Caretaker of the current Stable.

This can be harmful to the Caretaker, as he or she will not be able keep up with the information of both Warehouses and their brain will be overloaded.

If the reawakened Stable can be deactivated, then the Caretaker's flow of information will revert to its original state.

The same situation occurs when a past Caretaker is revived.

The Caretaker is organically connected to the Stable, as such as long the Stable lives they will live, but if the Stable dies they will die.
