An ancient magical relic known as The Looking Glass Theater awakens after Wonderland's magic begins colliding with Auradon, the Isle of the Lost, and countless alternate realities. To prevent history from unraveling, it summons six students from Merlin Academy into an enchanted theater existing outside time.

Inside, magic cannot be used to harm anyone, no one can leave until the viewing is complete, and every memory shown is completely authentic—even if it comes from another universe, the future, or an alternate timeline.

The theater can play anything:

• Alternate Universes

• Future events

• Past memories

• Original Characters

• Fan animations

• Music videos

• Memes

• Crossovers

• "What If..." scenarios

• Gacha reactions

• Alternate descendants

• Villain victories

• Hero failures

Every person reacts according to their own morals, emotions, and relationships. Nothing they witness changes their own timeline, but it may change how they view each other.
