Strike World and Strike Island
A multiverse containing the home worlds of all monsters. Each world has its own history and civilization, and is generally closed off from other worlds. However, it is possible to travel to different worlds using Strike Island's White Archive.
The White Archive
The White Archive is a huge library on Strike Island that houses books that contain the worlds of the multiverse. Each book contains one world as well as exhaustive information about that world. The White Archive is still home to many mysteries, with countless books eluding any attempt to decipher them.
