"At the centre of the Multiverse is a dimension called the Time Room, believed to be the quasi-corporeal dwelling place of the almighty Prismo. The Time Room is the single dimension that exists outside of time. The Time Room produces time waves that are experienced by other dimensions. Some dimensions have permanent links that allow travel to and from. Others become linked temporarily by naturally forming wormholes. And others can become linked artificially by magical portals, torn open by items of great power. An activated portal creates a time dilation in which either end of the portal experiences a temporal synchronisation allowing for the safe passage of particles through a non-local region of space-time."
