Door to Darkness

The Door is an object from the Kingdom Hearts games.

A trademark of the series, the Door is a tall, pink door first seen in Kingdom Hearts in the Awakening. Its appearance in a world marks the involved world's connection to other worlds (i.e. the Destiny Islands). The Door is used by the Heartless to travel from one world to another.

The true location of the Door is within a cave in End of the World beneath Bald Mountain. It is referred to by Ansem multiple times ("The Door is open.").
