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. Though it was destroyed, as it was being downloaded into the new ark made by the Earl, Allen brought the ark back in it's entirety by playing the piano within the ark's control room.

There are two arks. The original ark belongs to the Black Order since Allen rescued it, as it became "faulty" after the 14th Noah used it. Although anyone in the order can walk into it, only Allen can create gates at will and step into the ark wherever he wishes. The gates he create can be used by anyone else afterwords.

The second ark was created by the Millenium Earl after he downloaded the original ark into the new form. This downloading was mostly the effort of Road, though the Earl playing the organ most likely was necessary as well. The new ark was created because the old ark became "faulty" after the 14th used it.

The original ark could be controlled by the Earl, Road, and the 14th. It has currently only been used by Allen, though Road may still have some connection to it. The Earl's new ark has been used by Lulu Bell, but it is unclear if it is because she can use it at will, or if the Earl or Road helped her.

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.
