Inner Sanctum Access Key

A small, metallic key card with a ribbed edge and a single red light at one end. Romana handles it with practiced efficiency, inserting it into the authentication slot then correcting Tarak’s upside-down attempt—its orientation forcing a beep before proper insertion enables the door’s mechanisms to release. The key’s narrow profile fits snugly into the control panel’s narrow slot, its automated sequence triggering a metallic click as the inner sanctum’s door unlocks with reluctant precision.
