Plane Convergence
The infinite planes of the multiverse are constantly shifting their position in space, sometimes growing closer to each other or drifting further away. This slow motion can cause planes to occasionally overlap one another for a period of time, birthing a demiplane. This is called a plane convergence. The rules and laws of the child demiplane are a random mixture of the planes involved in the convergence. The energy generated from the creation of the demiplane is initially tumultuous as new lands and creatures form in this once empty space. As time passes, which varies based on the converging planes, the demiplane begins to settle, creating something truly unique.
While a convergence is usually a natural process, it can be forced by supremely powerful beings working in concert. Rarely is an individual strong enough to wield the arcane might necessary to do so, instead resorting to accelerating the natural motion of the planes to shorten the time span between occurrences. Many cults have prophecies involving sacred lands of salvation, often created by a convergence.
The random result of a convergence can easily create a demiplane more dangerous than the parent planes as the process is naturally chaotic and because the overlap most often involves the edges of planes which are generally the most extreme portion of a plane. Travelers to convergent demiplanes should be prepared for unpredictable environments and deadly creatures.
Mechanical in Nature
When a plane of constructs ruled by law, order, and efficiency converges with a plane of beasts and nature, it creates a demiplane at odds with itself. Law and order vying for control while the chaos of nature seeks unbridled freedom. The forces of nature are in a constant struggle against a mechanical army of progress.
The creatures of this demiplane are a mishmash of machine and beast. Each is dominated by either the chaotic or lawful aspect of the convergence, appearing slightly more beast or machine and behaving in a similar fashion. These creatures are often more powerful than their original form, gaining a complementing feature or trait.
