Mikeru's castle bears semblance to the Tower of Babel from the Bible. It spirales up and forms three peaks. Within one of the walls between the main castle and the outer layer is a staircase, leading all the way up to the main room of the castle and all the way down to the basement, where Mikeru's fossil sleeps eternally.
The castle is situated in Mikeru's dimension, which is filled with clouds, huge golden DNA-strands and extinct species.
