Night Palace

Night Palace is the seventh world in the Sonic and the Secret Rings game. It is the residence of Erazor Djinn, an evil genie who wishes to conquer the world using the seven World Rings. It floated away from the grounds of the Arabian Nights shortly before Sonic the Hedgehog arrived. However, the fate of the Night Palace after the defeat of Alf-Layla-wa-Layla is unknown. The palace has another dimention, one that resembles space. It appears once Erazor enables magic gates as a defense against Sonic. It also has gas rooms so rings must be collected to stay alive.
