The Realm of IIo is the dimension of the multiverse that contains the planet IIo. The Realm of IIo is the Realm that all other Realms are measured against by travelers. That is, the physics of IIo and the passage of time are both considered the multiversal standard. Other Realms frequently have altered physics and either slowed time or faster time compared to IIo. Some Realms with similar times include Lysia, the region around Oberon Castle, and some parts of the Aether Realms.
