The Grimhold is an inescapable magic prison that resembles a nesting doll (a Russian doll). It is featured in the film The Sorcerer's Apprentice. It has a total of four layers, each designed to capture one person. However, the innermost layer holds two people, Morgana le Fay and Veronica Gorloisen. They were captured and put into the Grimhold by Balthazar Blake.
Morgana was the first person to be locked in the Grimhold. Each sorcerer after her was trapped in the doll trying to release Morgana so she can complete a spell known as The Rising, an evil magic spell that will rise all the evil sorcerers from the dead, and create a perfect army for Morgana.
The contents of the Grimhold are as follows (starting from the innermost layer)
