|Keeper of Secrets|
Upon completion of the Abaddon's Gate mission:
- "You have done that which even the Five Gods were unable to do. For that you shall be rewarded. Please take this Book of Secrets. Present it to any of the Keepers you see here and they will reward you."
In the Throne of Secrets:
- "The Forgotten will forever honor your name."
- The name "Keeper of Secrets" might be a reference to the greater daemon of Slaanesh in the tabletop games Warhammer and Warhammer 40,000
