The Behelit is an artifact in the manga and anime Berserk. It is a small, oval object resembling an egg with a set of human facial features scattered randomly across its surface, giving the item a rather disconcerting appearance.
Reference is often made in the story to the fact that the Behelit looks to be a living thing, and it emits a certain aura of unspecified dread. On occasion, it seems as though one of the Behelit's eyes opens and stares at the examiner, though this is usually quickly disregarded as merely an illusion.
Purpose and Usage
Behelits are the keys to open the gate between the human world and the bottom of the Abyss, where the God Hand reside. They belong to their destined owners and cannot be permanently lost or discarded until they have been used. When the destined person's desire to escape his current situation is great enough, the behelit will find its way to him or her, and call forth the God Hand to grant the wish with a fitting sacrifice. When this happens, the facial features of the behelit rearrange to form a face, crying blood and screaming. This is the primary means through which humans are transformed into Apostles.
Griffith's Crimson Behelit, which he obtained from a fortune teller as a youth, was a rare and unique item as Zodd called it the 'Egg of the king'. It appears once every 216 years when the time of the Eclipse draws near, and rather than becoming an Apostle, the bearer of the Crimson Behelit is destined to become the next member of the God Hand. During the Eclipse, Griffith uses the Behelit to sacrifice everyone in the Band of the Hawk in order to become Femto, the fifth member of the God Hand.
