Aetercerem

Aetercerem, from Aeternum Carcerem, the Latin translation of "Eternal Prison", was created as a prison for the creatures that were later to be known as the Aetercerians.   It was created by Cipiurra by order of her parent deity Heocanin.   Aetercerem made its inhabitants see and experience whatever they needed to experience to remain imprissoned. Since its breaking, Aetercerem has become imperfect in keeping creatures in. They will eventually realize they are in a prison and some will try to break out, others are content with the prison and remain.   The idea is taken from the Matrix, a simulation where humans are led to believe they are living normal lives so that they won't wake up to the real world.
