Corentin Location in The Sinking City 2

Quick Answer

Corentin is on the second floor of the Miskatonic Library Annex. From the library objective, enter the Library Annex, push through the Restricted Section, take the Ritual Book, move the cabinet that blocks the exit, then continue up to the second floor until you enter Corentin's room.

Do not leave immediately after the Corentin scene. Pick up the E.R.C. Activator Pen and E.R.C. User Manual near him before exiting the Annex.

Who Is Corentin?

Corentin is a named character connected to story progression and investigation routing in The Sinking City 2. Players usually search this name when they need one of three things: the character's location, the quest step connected to him, or the nearby E.R.C. Activator Pen.

This page keeps the first answer spoiler-light. If you need full route order, pair it with the The Sinking City 2 walkthrough.

Where to Find Corentin

Use the library investigation route as your main signal. The path is:

  1. Enter the Library Annex from the library objective route.
  2. Continue into the Restricted Section.
  3. Take the Ritual Book when the route points you to it.
  4. Move the cabinet that blocks the exit.
  5. Go upstairs to the second floor instead of leaving the annex.
  6. Enter Corentin's room and finish the scene.
  7. Before moving on, pick up the nearby E.R.C. Activator Pen and E.R.C. User Manual.

Before you move on from Corentin's area:

  • Read documents, letters, and clue text near the objective.
  • Check every available dialogue option before ending the encounter.
  • Search the connected upstairs rooms before returning to the main route.
  • Pick up the E.R.C. Activator Pen before leaving the Annex.
  • Reopen the Investigation tab and confirm new clue links were added.

Quest and Story Requirement

Corentin is part of the story/investigation chain around the library route. If your objective log, dialogue, or clue chain points to the Library Annex, finish that chain before chasing optional exploration.

If the route is blocked, check these common causes:

ProblemWhat to Check
Corentin does not appearConfirm you reached the Library Annex, Restricted Section, Ritual Book step, and upstairs route.
Dialogue seems exhaustedReopen the Investigation tab and look for a new linked clue or location prompt.
The pen is missingFinish the Corentin scene, then check the nearby safe-room/user-manual area before leaving the annex.
The next step is unclearReturn to the upstairs rooms and search interactable notes or side rooms.

Can You Miss Corentin?

Corentin is tied to the library investigation path, so the main risk is not "never seeing him"; it is leaving the annex before collecting nearby evidence and the E.R.C. Activator Pen. Treat the area as complete only after you have checked the upstairs rooms, taken the pen, and opened the earlier E.R.C. Crate.

What to Do After Finding Corentin

After you find Corentin, slow down and clear the encounter before advancing:

  1. Finish every dialogue branch.
  2. Inspect the room or surrounding route for readable evidence.
  3. Pick up the E.R.C. Activator Pen and E.R.C. User Manual nearby.
  4. Open the Investigation tab and confirm whether a new clue, location, or case link appeared.
  5. Return to the earlier Library Annex E.R.C. Crate and open it.
  6. Continue through the story walkthrough if the next destination is unclear.
