Where are Don Corneo's hiding places?
Don Corneo has three different hiding places that you can find in Chapter 14, along with some hints of their location. The first two are the ones you've probably seen in the past and just didn't know, with the third actually related to the story you'll need to find along the way.
The first of Corneo's hideouts is in the collapsed expressway, so use a Chocobo to get to the start quickly. Enter the collapsed expressway, but almost as soon as you enter, take a left and you will see a path with a gate with the Don Corneo logo on it. Go up and you can now open this door, so do so and put all the items inside.
Next, Corneo's second hideout is around the Sector 5 slums, so get there by traveling quickly. Once you are there, exit through the northeast exit of town and follow the correct path until you come to a large wall. From there, don't climb the ladder, but instead go through the next door and you will see a staircase to the left. Go up this staircase and you will find the second of its hiding places.
Finally, the third and final Corneo hideout is located in the sewers, which you cannot access on your own. Instead, you need to go to Corneo's mansion and find Leslie. He'll help you get back to the sewers and go on a long mission to find Corneo, which you'll end up doing. This ends with a boss fight before leaving the sewer area.
Before we leave, we want to find Corneo's hiding place here. You will eventually do this and be able to unlock the door. However, you will notice that the room is filled with water and you cannot enter it anymore. This means that you have to go further down the path and eventually find a terminal that allows you to lower the water in that room. Go back to this room and collect the remaining hidden objects and you will have the three hiding places.
