Meta-World

Purgatorio, also known as the Meta-World, is a secondary dimension in Umineko no Naku Koro ni, separate from physical reality. Purgatorio is seen as the witch's realm and is where the "games" of Umineko no Naku Koro ni take place. Any fragment of reality may be viewed from Purgatorio. It is implied that Purgatorio is some kind of afterlife.

Most of the debating between Beatrice and Battler take place in the Witches Smoking Room.

In Ougon Musou Kyoku, either team may attempt to enter Purgatorio for significant advantages and powerful moves.
