Where to Use the Old Key in Clair Obscur: Expedition 33

The old key opens a **gate in Old Lumiere**, which is tucked away on a side path you’ll encounter in act two. When you reach this area, your party will split up.

- Start at the **Expedition 42 – Left Street** rest point with Maelle.
- Head down the hill into the open space with a sword.
- Walk through the broken archway to your right.
- Immediately past the fallen windmill, take a right.
- Look over the ledge to spot a big pipe with a hole in the middle.
- Drop down through that hole and turn around to discover a locked grate.
- Use your old key to unlock it.
Behind this grate, you’ll find a hidden **Survivor log**. These logs give you juicy story details about the inhabitants of Old Lumiere. Trust me; you’ll want to find out what’s going on—you’ll be glad you did.
