11th Seat of the Black Scripture

The 11th Seat of the Black Scripture. She is commonly known as the "Thousand Leagues Astrologer". She is in charge of providing intelligence support to her team.

Personality
She seems terrified about the horrible event that unfolded in the Katze Plains, where Ainz used his super-tier spell to massacre most of the Re-Estize's Army.

The Bloody Valkyrie Arc
She, along with the Black Scripture encountered a powerful vampire and tried to capture it but failed. Two of the Scripture’s members were killed, while Kaire received a critical injury. The Captain of the Black Scripture ordered her and the other members to retreat and leave it alone.

The Lizard Man Heroes Arc
She was briefly mentioned by Zesshi Zetsumei, when talking about her prophecy of the Catastrophe Dragon Lord's revival with the Captain of the Black Scripture.

The Ruler of Conspiracy Arc
After observing Ainz's massacre of the Re-Estize Kingdom's Army at the Katze Plains alongside the Baharuth Empire, she became a shut-in, staying locked up in her room for an unknown period of time. One of the cardinals from the Theocracy thinks that she has fallen into despair or suffered some sort of shock. Presumably, the cardinal believes she saw something that not even the Godkins may stand a chance against.

Abilities and Powers
She seems to possess some form of surveillance magic from afar, identifying to some degree the number of soldiers Ainz Ooal Gown has under his command. While so, she is able to predict the Catastrophe Dragon Lord's revival.

Trivia

 * In the Web Novel, the 11th seat was classified as a male.
