I play on GOG so couldn't make a guide here (Don't own the Steam version). But I wanted to share the excel sheet I put together to track the weekly locations of the different characters. If you copy and paste the below text into excel it should put everything into the proper cells to make it easier to read (I also have color codes and lines to help visually, but that gets lost in the copy paste). Also made a table of Scrolls so you don't have to research every ??? and clutter your inventory. Finally added some Notes for things I would have liked to known before jumping into this adventure.

Notes: Have to use Reishal scroll on Firefly first, or risk a task breaking glitch between hers and Violets picture.
If you tell Firefly about the Dungeon Passage she will hang a blanket over the Noble Room spy mirror. On cold blizzard days, she takes the blanket down so you can still spy there.
Elsa's dresses are currently not used in the game, nor is there a way to get a towel for Violet (Developer Comment December 2023).
Don’t Exorcise the Camilla Daemon (Nun) with the Damned Stilleto, untill after getting Firefly's true name from the Nun.
When the Bond Maid Camaria gives you a pouch. Use the pouch to get the pearls inside, before giving it back to her on the outdoor map. Otherwise the quest will end prematurely.
To find the Runaway Bride Diana, you have to go into the Catacomb level 1 gem mine, then move east to a secret room.
To trigger the event for the Princess to ask you to assasinate the Priest, you have to allow the Priest to fully complete Priests Investigation task.
There are various ways to complete the game (some being an untimely death).
Ultimately you have to let the Forces of Darkness take the Keep to get the different endings and finish your playthrough.
