Oblivion:Blind Moth Priest

From UESPWiki

Blind Moth Priests are the Monks that read the Elder Scrolls in the White Gold Tower. As a result of reading the Elder Scrolls over their lifetimes, they eventually lose their sight.

Blind Moth Priests can be found during the quest Turning a Blind Eye. They are the guardians of the Savilla Stone, the first item the Gray Fox requests during the strand of quests you do for him in the Thieves Guild. Although they are blind, they can still detect you just as well as a normal person could and are also affected by Chameleon and Invisibility. They favor Akaviri weapons. These NPCs are also the priests from whom you steal an Elder Scroll during The Ultimate Heist quest.

The Temple of the Ancestor Moths is an excellent source of enchanted jewelry. It is the best place to find rare items such as the Ring of Perfection and the Mundane Ring.
