Agents who have died or left the warehouse have their personal effects sealed in their quarters (effectively, their room at Leena's Bed and Breakfast) and kept in a massive electro-mechanical indexing system deep inside Warehouse 14. The means of removing, sealing, transporting, and storing the room is not fully explained. Once stored, a retired agent's quarters is given an index number which is attached to their personnel file in case of retrieval.
If an agent's effects need to be retrieved for any reason, an access door can be used to reach a particular agent's sealed quarters, by entering the four-digit index code on a rotary dial, which then displays the number input on four 'Nixie' indicator lights.
