Keep
From NEStalgia
The Keep is the inner section of the Black Sanctum and can be accessed by completing the Eye See What You Do There quest. If a player resets their daily quests they lose access to the Keep and must re-complete the aforementioned quest. Two of the seven Black Sanctum quests (Small and Smaller and Malicious Intent) can not be started nor completed without Keep access. One of the five remaining quests (Ghost Hunt) occasionally will require access to the Keep in order to find the Specter related to that day's quest.
