Go to the Cheydinhal Bridge Inn in Cheydinhal. Once inside, turn right and go to the wall with 3 barrels lined up (2 small and 1 big one). Jump onto the middle barrel and walk towards the wall very slowly and carefully. you will walk straight through into black. there is a ledge just big enough to drop onto. Turn right and edge around the corner very slowly. Follow the ledge and when you get to the end of the ledge you can go nofurther. Drop down towards the door but keep the left analog stick held forwards so you are still moving forwards. There is a chest suspended in mid air underneath the building. I have checked the basement and it isn't in there! When falling, you have to time it right as to press X when falling past the chest. It says it requires a key. I do not know where to find this key though. If you find the key and open the chest, e-mail me to tell me where the key was and what was in the chest. Note: Don't worry if you miss the chest. You will fall but land back inside the inn somehow. Good luck!
