The Sorcerer's Key



The Sorcerer's Key, also known as the "Sorcerer Key", is a magical gold key that is used to trap in his underground prison and also to set him free. It made its debut appearance in the titular episode "Randy Cunningham and the Sorcerer's Key" of the Randy Cunningham 9th Grade Ninja cartoon series.

History
Before Randy and Howard ruined the timeline, the key was used to close the Sorcerer's prison after the Sorcerer got trapped by Eye of Eternites. When the key is found, the NinjaNomicon stores its key until the key itself moves to a different location. Everytime the key reveals its location, the Sorcerer tends to fail from getting the key. During "Ball's Well That Friends Well", the Sorcerer was released from the prison to fight against Evil Julian. The Sorcerer's Key is a magical artifact used by the First Ninja to seal the Sorcerer's prison. Afterwards, the Ninja hid the key away, knowing it was far too dangerous to possess. Once every century, for one minute, the key's location will be revealed when the sunlight reflects off the Eye of Eternity. Once it's been found, the NinjaNomicon (Nomicon) stores the key until it relocates.

The Sorcerer himself has always tried to get his hands on the key, but it has always evaded his grasp.

Trivia

 * So far, the Nomicon (NinjaNomicon) interpretation of opening the prison is different from reality.
 * The episode's title may be a reference to the title of the first Harry Potter book, "Harry Potter and the Philosopher's Stone", and it's movie title, "Harry Potter and the Sorcerer's Stone".
