The Nexus, flows through Creation, just beyond physical reality, providing mystical energies that underpin all that is or will ever be. It is the force that powers magic. It is from which Creation emerges.
Periodically, the energy of The Nexus erupts geyser-like into the physical reality. These areas are called Nexus Points. After spewing nexial energies into Creation, Nexus Points often collapse unto themselves. That wild and raw power is absorbed by Creation and used to support what already exists or to create new formations.
There are, however, a few Nexus Points that are more “stable,” if such a word can be used, like the one at the center of what has come to be called “Rhedrin.” The “world” of Rhedrin is not truly a world. It is a platform of Order. It is a dimension unto itself.
These “stable” Nexus Points are places of high ambient magic. They continually express nexial power into Creation. From these places, entire worlds or dimensions are formed as they flow further and further away from the Nexus Point, which birthed them. This is not the only way creation evolves, and sometimes, the nascent realms fail, only to be absorbed by other parts of Creation. Nexus Points have been called “Fonts of creation” due to this phenomenon. Given their nature, Nexus Points also tend to be arcane crossroads, connecting all places in Creation.
On rare occasions, when the power released is too much to be absorbed quickly, a Chaos Storm can form. It will ravage worlds and dimensions as it traverses Creation. Over time, its chaotic energy is consumed until all is orderly once again.
