On Dimensional Theory: Portals and Instability
There are an innumerable amount of Dimensions, and several Dimensions have already been identified. However, without the aid of Portals, it would be an impossible task to discover any further Dimensions.
Portals are the gateways that enable their users to travel from one Dimension to another. Portals can come in many forms, such as a door that may directly lead to a specific point in a different Dimension or a book that will instantly teleport the reader to a different Dimension. It is currently unknown exactly how Portals work, as Portals are often a mixture of technology and magic that is incomprehensible to the typical dimensional traveler.
It must be acknowledged that any form of dimensional travel will generate an amount of Instability. The more abruptly a dimensional traveler crosses from their Dimension to another, the greater the amount of Instability.
Instability is the amount of disturbance in the natural order of the Multiverse and dimensional travel will increase the amount of Instability within individual Dimensions. Dimensional travel involves the transportation of one being from the Dimension they were residing in to another Dimension, and this process requires a large amount of energy, which is typically drawn from the two Dimensions. The energy lost in dimensional travel is then reclaimed by the Dimensions in a different, more ‘hostile’ form and generally causes havoc. Left unchecked, Instability can destroy entire Dimensions.
One of the many destructive effects of Instability is also its most defining feature: spontaneous dimensional travel. Unstable Dimensions will often generate Portals in unorthodox locations, and any being unlucky enough to stumble upon these Portals will be forcibly transported to a random Dimension. These Portals often close just as abruptly as they appear, leaving the victim in a foreign world that may possibly be their end. This effect only serves to further feed Instability, as it is merely another form of dimensional travel.
