Noah's Ark

Noah's Ark is a large structure that contains many rooms, and serves as an important asset to both the Black Order and the Millennium Earl. It is destroyed, but then is brought back while Allen is playing the piano. WARNING ! The following is pure speculation and should not be treated as concrete facts! It could be, that the Ark itself, is a dimension, with doors that open out into other dimensions, and doors that open into other worlds, and that the cube like form of the Ark, is nothing but another door of the true Ark, which could be humongous it size.
