Bug subject (Graveyard Keeper)
Went down to the basement of the Church in search of the diary for the astrologer, and no diary.Maybe you can make via the console? It further makes no sense to play
Sneek22 correctly written. Have to open with a key grating in which there is a Serpent (the evil man) and move on. Diary in one of the rooms.
There is the following sequence of execution: a talk with Astrologer -> get the key of the guardian (dark this) -> to talk with the Serpent, get instructions from him for the key -> on the research table in the basement of the Church to activate the key (give another gold, activated) -> after talking with the Serpent to open the grate in the course of cut scenes with him to visit, discover the entrance to the cave, and simultaneously also the room with the diary -> go into the room (still cut-scene) -> suicides (cut-scene) -> resurrect -> to enjoy immortality> go back and pick up the diary.
You can then go to the Stargazer, or to continue the dialogue with the Serpent and get the dungeon cleaned, but that is another quest in fact.
