Blueberry Hill

Origin
It is currently uncertain how this hill was truly formed into an artifact. However, it is known to have inspired the song “Blueberry Hill”, the most famous version sung by Fats Domino, “I found my thrill on Blueberry Hill”.

Effects
A entire (though smallish) hill located in the Warehouse, anyone who climbs to the top will find what they most desire, be it an object, person or even an abstract concept like a view or sound. This only lasts while on the hill, and things cannot be taken from it. The desired object must have some sentimental value to the person, and simple greed will yield no result.
