As you explore the area, you will find that people have turned into monsters, with the reason being unknown.
As you keep progressing, you will eventually arrive at the St. Frangelico Cathedral Library, where you will find Cecile, the only survivor who doesn't want to become a monster like others, making the beginning of her quest.
Keep reading our guide as we walk you through Cecile's entire quest by going over how you can get Cecile's side quest, where to find the key item required for completing the quest, the Archbishop's Mark, and the two endings for the quest that you can have.

How To Get Cecile's Quest In Lies Of P
You can get and complete Cecile's quest in Lies of P once you are at St. Fragelico Cathedral Library. Once you are there, from the Stargrazer, head to the room on your left.
Near the door blocked with wooden planks, you will find Cecile. Talk to her and exhaust her dialogue options to trigger her quest that requires you to find the Archbishop's Holy Mark.
Where To Find Archbishop's Holy Mark In Lies Of P
You can find the Archbishop's Holy Mark in his room on the first floor of the St. Fragelico Cathedral Library, which you can get to by following the path on the left side from the Stargrazer.
Firstly, take the path on your left from the St. Fragelico Cathedral Library and stick to the left wall to ensure you don't trigger the ground trap.
Once you are past it, turn right, defeat the monsters, and take the stairway. Stick to the left path, head down the stairs, and stick to the left side again.
Now, take the stairs on your left, as shown in the above screenshot, and then keep following the path until you reach a hall with the elite monster.
Defeat him or run past him to the stairs as marked in the above screenshot, and keep moving while looking on the right side.
At the end of the room, on the right side, you will find the platform leading to the Archbishop's room.

Lies Of P Cecile's Quest Good Ending
You can get the good ending for Cecile's quest in Lies of P by giving her the Archbishop's Holy Mark before the Fallen Archbishop Andreus boss fight. Once you do that, after you defeat Andreus, head back to Cecile's location, and you will find two items:
- Cecile's Written Confession
- Divine Service Gramophone Disc
Reading the letter, you will realize how you helped Cecile live as a human, unlike every other poor soul who already succumbed to the mysterious disease and become a monster.
We recommend reading her confession letter as you get the Pray gesture as an additional reward for Cecile's quest.
Lies Of P Cecile's Quest Bad Ending
You can get the bad ending for Cecile in Lies of P by not giving her the Archbishop's Holy Mark before defeating Andreus. When you do that and return to her location, you will find she has become a monster but with some consciousness left.
She will tell you that now it's too late and all that and will start attacking you. Killing her will give you a Vivid Ergo Fragment, which is nothing in comparison to the reward that you get from the good ending.
That concludes our guide on Cecile's entire quest in Lies of P. For more on the game, check out our dedicated Lies of P section.
