Curator Ashworth's Office is located on the third floor of the Royal Conservatory, at the west end of the atrium. It consists of an outer area where her assistant's desk is located and a small seating area, presumably for guests. Double doors then lead into the office proper. If you enter the office without sabotaging the Oraculum beforehand, there is a gravehound on guard inside.
Once inside, search the area reveals a flask of S&J Health Elixir and one of Addermire Solution, a Proposal from Curator Haden and a life-size, talking statue of Delilah.
Her desk contains a note from a cleaner with a key (which key ?), an Unfinished Letter to Delilah, and some Pistol Bullets. A staircase behind the desk leads to a small landing with a painting. At the top of the stairs is a display case with a Broken Whalebone Sword.
