Sixteen Planes of Morality

The Sixteen Planes of Morality, also known as the Outer Planes are a series of sixteen dimensions of reality that are molded around different concepts of morality that affect sapient beings. They are generally understood to be more distant from the Material Plane than the Elemental Chaos, Elemental Planes, Ethereal Plane, Feywild, and the Shadowfell, however more closely connected than the Positive Plane and Negative Plane.

Gods & morality
The most notable inhabitants of the Sixteen Planes of Morality are the gods of the Thunderous Cascades universe. Because the existence of gods are dependent upon the mental energy that their followers direct towards them, the existence of the planes themselves are dependent on having a sufficient number of sapient beings within the Material Plane, Feywild, and Shadowfell adhering to each classification of morality. In some instances, if there is a sudden drop of adherents to a god or to a path of morality, the god or plane may weaken or temporarily cease to exist. This often results violent chaos developing in the nearby planes as the balance of the universe is thrown off, and typically continues until the former plane's niche can be restored.

There is no plane for neutrality, as the Material Plane suffices to be the area where all of the concepts of morality coexist.

Afterlives
The Planes of Morality are also where the spirits of deceased sapient beings go for their afterlives. Sapient creatures who are of a neutral alignment are sent to either E|Elysium, Mechanus, Hades, or Limbo, depending on which concept of Goodness, Lawfulness, Evilness, or Chaos they mostly closely strayed towards during their lives. When beings are in their respective afterlife planes, they appear as their species' equivalent of 30 human years old.

Animals that are capable of developing personalities, such as cats, dogs, horses, primates, etc. usually go to whichever plane most closely corresponded with their behavior during their lifetime. Animals kept as pets will frequently join their master(s) in their afterlife plane, however this will not happen if their animal-like moralities conflicted with that of their master's.

Animals that are not capable of higher cognitive processes, such as most insects, fish, and simpler life forms usually go to a plane that corresponds with the behavior of their species, which is more frequently on an axis of law and chaos than an axis of good and evil. For example, bees and ants often go to Mechanus, Arcadia, and Acheron, while centipedes, solitary worms, and spiders go to Limbo, Ysgard, and Pandemonium.
