In Puella Magi Madoka Magica, witch's labyrinths, also called "barriers," are dimensions consisting of both elements from the present location in reality and allusions to the witches that create them. Deeper within the labyrinth, more references to the witch will be seen and fewer elements from reality show up.
This tag is used for posts with references to the labyrinths that appeared in the anime, or similar scenes that are clearly drawn based on original labyrinths.
