Senntisten scrolls are items found randomly while skilling in The Empty Throne Room. They should be returned to Celia Diggory, which unlocks the ability to claim a transcribed copy from her. Each scroll unlocks one of the four books, in a specific order:
- Letter signed 'Pontifex Madromurt'
- Letter signed 'Pontifex Nabor'
- Letter signed 'Pontifex Bilrach'
- Damaged digsite letter
When investigated, it says "Celia Diggory at the Senntisten digsite would be interested in this."
- Sentient Letters ( 15) - Collect all the letters from the Senntisten digsite.
