Ark Cradle

Ark Cradle (箱舟幼時, hakobune yōji) is an artifact created by the three great families prior to the Grand Migration. It was said to be the perfect vessel to travel between dimensions such as the void between Sonoma and Kanna, but also between worlds, as seen when N used it to travel to a parallel universe where Hikaru originated. It is said to resist Reason by an unknown method and it indestructible. This vessel can only be used by a being originating from one of the ancient families however, only the one who is chosen by the ark may completely control it.
