Eddie is also testing out floorboards, keeping his eyes down and trying to do his best not to sneeze or cough in the dusty, spore-filled air. After some time, Eddie sees that glint and says, "Hey, there's something shiny -- over this way." He points, but a moment later moves toward it.

Eddie sets his lantern on the floor, close to the shiny thing... and sees that it's a latch. When he gets the floorboard up, he draws his dagger and pokes around with it in the space below... just in case. You never know when you might run into a hostile squirrel or something.

But there's no animal life down there... just a small box.

Eddie pulls off the lid, and sees the silver locket within. His voice is more hushed as he asks Milo, "Do you think this could be the anchor the letter mentioned?"
