The Behelit, also known as the Egg of the King or the Crimson Behelit, is a mystical artifact from the dark fantasy series 'Berserk' created by Kentaro Miura. It is a mysterious, egg-shaped object with human facial features that, when activated, opens a portal to another dimension. The Behelit plays a crucial role in the series, serving as a key to activating the God Hand's power. It is essential for characters seeking to transcend their humanity and become apostles, but at a great personal cost and sacrifice.
