Limbo

Limbo is the home of the Virtues. It is a bleak and empty place, in stark contrast to the Spirit Realm that is the home of the Sins. Aside from Fluffy, a host, no other mortals are known to have ever seen or entered Limbo. In contrast, the Spirit Realm has had no human visitors; Lust claimed that it could pop the mind of a child. Whether this is true remains to be seen.

Limbo appears to be made up of various rooms and chambers, despite its overall white color. It is quite possible that the empty, boring expanse is partly the reason for the bitterness of the Virtues, especially since they are locked in their positions.
