Editing Planes of Existence (section)

=== The Elemental Swirl ===
The Elemental Planes are constantly swirling in a direction toward the Material Plane. Although they “circle” in this way, this effect is not noticeable while on a particular plane, other than an obvious day/night cycle. Elemental planes have a four-part orbit cycle, as described below.

==== Day ====
Day is when a particular plane faces the Positive Energy Plane. Planes are rejuvenated during this part of the cycle, while Quasi-elemental planes formed via the Negative Energy Plane are kept from dissolving back into entropy.

==== Sunset, or Osmosis ====
Toward the end of the Day cycle, Elemental planes touch the barrier of the Material Plane. During this time, elements from the various Elemental planes are siphoned via osmosis into the network of tunnels of the Underdark, to be deposited within each Material World. This process is depicted as a swirling of the elements of the plane as they are hoisted into the air.

==== Night ====
Then, the plane faces the Negative Energy Plane, where it is dark and Entropy attempts to bring decay and disorder into the plane itself. For this reason, night is particularly dangerous in the Elemental planes.

==== Sunrise, or Prismrise ====
As the plane  begins to face the Prism, the sunrise is represented by swirling colors in the distance, with the Elemental Chaos in the distance as well.
