Dimension

Pocket universes are the parallel universes of the Multiverse.

Background
Quantem theory allows for these "pocket universes" to have their own unique sets of the laws of science and nature. Another theory states that the universe is not made up of individual particles, like atoms or electrons, but instead composed of strings--strange things that are long, but not high or wide, and have other dimension. This theory only makes scientific sense, however, if the universe has more than the four dimensions to which most are accustomed to; 26 dimensions is one number given. The reason that people do not see the extra dimensions is that they're folded up on themselves, but they are there, nonetheless. These could be pocket universes. Daventry may be one of these pocket universes.

Daventry is said to exist on one of these pocket universes, separated from twentieth century earth (perhaps even in Earth's past through a time warp), but connected via wormholes, and other methods often by magic. It was peopled by people from Earth. The world has its own history, that has developed on its own, but has been influenced by those who withdrew into the realm, or by dreamers from the Other World who are able to change it with their minds. The greatest of these dreamers was the great sorceress Roberta Williams. It is said that her dreams started to change the world, and its history. Perhaps creating more alternate dimensions split from the original.

Pocket Universes

 * Assorted individual locations in the Multiverse
 * Original Daventry (the daventry of King's Quest AGI to KQ8 (with some variant alternate timelines).
 * Daventry 2 (a parallel timeline seen in King's Quest I SCI, but largely irrelevant)
 * Daventry 3 (the timeline as it appears in King's Quest (IX), at least contains yet another retelling of King's Quest I)
