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.
- So far, the Nomicon interpretation of opening the prison is different from reality.
