The research you previously succeeded on in this part of the Dark Depository
The Dark Depository primarily contains knowledge deemed too dangerous for general use. Numerous references to interrogations can be found, including mentions of the Scrolls of Inquiry, recording the confessions of members of the Sacrosanct Order of the Blue Feather, a sect of Nethysians who were questioned immediately after the death and burial of Hakotep I. The fact that the members of the sect were priests and priestesses of Nethys was kept secret, as Nethys was much revered in Ancient Osirion. Hakotep’s successor, Djederet II, was a priest of Nethys himself, and he deemed that the potential backlash of such information becoming public could lead to dangerous civil unrest.
You undoubtedly have the right place, but further research is needed to uncover the Scrolls of Inquiry.
