A mysterious object that was found in the possession of the World Magic Bureau Federation/Iceberg Branch, it was taken during the scuffle and confusion of the attack launched by Sub-Zero and Naazariya in X793.

Description
The object while called the Forlorn Heart, is actually a cube shaped object that has what appears to be a small demons face and several closed eyes. Complete with an inside compartment that has a small indent within the inside. The object earned its name because the objects unusual ability to "beat" as a heart when it is near other objects of Zeref, honing on to them as a beacon. The closer the object is to the heart the stronger and more violent the heart beat. This object served as a priceless method for how the WMBF located and found many of Zeref's creations and objects. The 4 green switches on the Heat can be caliberated to locate and change the level of search from close range to far seaching for inanimate and living objects of Zeref such as Etherious and other living creations that were used by the Black Wizards Magic. This Heart is now in the possession of Tartaros per being found and taken by Naaza and Sub-Zero. The Heart also has the unique function of releasing "Seals" and acting as a key to remove/destroy locks that Zeref himself may have locked or another.
