The Missing Prisoners is a Quest in Divinity: Original Sin II. Somehow, there are many missing prisoners in Arx after the Paladin coup, hinting at something sinister afoot. Can you discover why?



Important NPCs

  • Isbeil
  • Paladin Warden



The Missing Prisoners Objectives

  1. Find clues of the missing prisoners.
  2. Read Isbeil's notes.



The Missing Prisoners Walkthrough

Enter the prison and talk to the Paladin Warden there. You will learn that the Magisters have been investigating the disappearances of many prisoners from their cells beneath the Magister Barracks, prior to the Paladin uprising. This quest is relatively straightforward, but since it is tied with "The Secrets of the Dwarves" quest, you may wish to look there for a more detailed walkthrough on how to get to Isbeil.

In any case, after you defeat Isbeil, you will find the missing prisoners in her laboratory, who have all been drained of their source, as a kind of experiment. In order to get there, take the illusory door on the left side (map wise), not the right, since the right one leads to a deathfog trap. In any case, once you reach Isbeil's laboratory, search through it and find two items that you must read for the quest to progress - Isbeil's Notes (renamed to Isbeil's Research Notes when read) and Isbeil's Research Journal. Doing so  will complete the quest, earning 96,950XP.

Make sure to return back to the Magister prison and speak to Paladin Warden Yona in Arx Prison. You will earn a choice of Common-quality loot as a reward for reporting of the missing prisoners' fates.






  • 96,950XP upon completion of the quest.
  • A choice of Common-quality loot upon reporting back to the Paladin Warden.

      I choose to spare Justina but then as she was walking away she ran into death fog and died. Oh well, looted her body for key that unlocks chest in her bedroom.

            There is a second book near the bone altar where the prisoners were drained of source. There is also a secret safe in the wall to the left of the bone altar which had a legendary and divine item in them.

                  To move the quest forwards you need to read the "Isabel's notes" located in the corridor near the drained sourcerers
