This is the first game in the Ghosteze (Series). Mario And Co. make apperences but are'nt playable. A Ghosteze is a spirit that has it's own yin and yang to help guide it. The video game is on Nintendo Wii and is an adventure/Action featuring elements from the marioverse even though it is not a part of the series. The pool of darkness is The Spirit Yin's home. Ghosteze needs to visit The Spirit Yin. It is not Yin but in a way, Yin is in ghosteze! The Spirit Yin has the power and wisdom to break one of the Wane spirits that block the yin in a ghosteze.
Mario And Luigi were walking over to princess peach's castle when the star spirits were flying around franticly.The Sky turned black! The spirits got trapped in a black hole!
