The Dream Castle of the Pentacle Mirror (夢幻城, Mugen-jō, "Fantasy Castle") was the residence of a daiyōkai by the name of Princess Kaguya. It consisted of a typical Japanese palace, and rested on the surface of Lake Motosu, supported by stilts. The floors of this castle were strewn with cherry blossoms. Behind the castle lay a large rock, on top of which was Kaguya's main hall: a massive structure supported by large wooden columns. The castle was apparently raised from the bottom of the lake by Kaguya, but it was only an illusion. The real castle lay within the "Realm of the Night" a mirror world connected to Lake Motosu. This was known as the Castle Beyond the Looking Glass. The castle was destroyed after Kaguya's demise.
