The Four Realms

Empyrean
The Gods reside in Empyrean where light magic in its raw form reigns.
When someone dies their soul passes into Empyrean unless it is corrupted by darkness. No mortal living being can enter or their soul is absorbed into the realm and the body ceases to exist in mortal form. They could never leave again. It’s a one-way path for deceased souls.
Light magic is at its most powerful during the full moon and during summer solstice.

Orlon
The Magical Realm comprises a single world called Orlon. The Gods siphon their magic into Orlon via conduits such as God Tress, heirs and magical beings.
The magical beings that live in Orlon oversee the magic, all life, and control of nature, balance, and order.
The trees are a bridge between Empyrean and Orlon. Magic from the God Tree Roots extends to the living realm and all the worlds granting life but nothing more as the magic cannot extend but so far from Empyrean.
Water is a conduit for travel between the living realm and magical realm.
Orlon is as big as it needs to be to contain its inhabitants and acts a refuge to anyone and anything in the universe that needs it. ​
Orlon stands guard against demons and evil spirits escaping from Mokor.

Mokor
Only dark corrupted magic exists in Mokor.
There is no God that reigns over Mokor. It is run by chaos and darkness.
When someone dies, if their soul is corrupted by darkness they are damned to Mokor to spend eternity suffering. They will always be hungry. They will always want for touch but only feel pain when they are touched.
Demons who cross into the magical realm or living realm are rendered incorporeal and must possess a body in order to exist for longer than an entire moon’s cycle. If they don’t possess a body within that time they turn to dust. If they do possess a body it won’t last long before the body dies because the demon is like a cancer that kills its host. So they either need to jump to another body or go back to Mokor.​
Just as with Empyrean, no living being can enter Mokor. If a living being enters Mokor its body is devoured and the soul that remains is a husk who feels only pain, despair, and longing forever.
Dark magic is at its most powerful during the new moon and winter solstice.

The Living Realm
The Living Realm comprises Earth, along with all the other known planets in the universe.
A little magic exists in everyone. That’s life, love, consciousness, your soul, etc. But that’s the extent of magic in this realm except for beings who travel there from Orlon.
The Balance of Life and Magic
Think of the universe as a large scale: Mokor is on one pan and Empyrean is on the other.
Orlon is the base and beam that supports the entire structure, dolling out the magic equally.
Light cannot exist without the darkness, but 97% of all living creatures in the universe are inherently good. That means that if you balanced the scales of life on simply good vs evil. Good would overtip the scales and destroy the balance of life.
In order to keep the scales from tipping, The Gods created the living realm.
Every world in the universe orbits around and within the workings of the scale providing a weightlessness and a buffer, never allowing either pan to drop.
The realms are separated by veils.
Without a Druid the veils vanish completely and the scales break. Everything in the universe would be destroyed, including Empyrean and Mokor.
Mokor wants the Druid to exist to prevent cataclysmic apocalypse but they want to corrupt the Druid to prevent them from resealing the veils when they become thin enough to bass through.

The Hierarchy of Magic
Light Magic: All that is good. The entire universe and the balance of life depends on light magic that originates from the Gods in Empyrean. We all have a little bit of light magic in us that is the spark of life.
Innate Magic: Exists beyond our understanding or comprehension. It simply is. It cannot be manipulated, modified or nullified by any person or substance.
Tangible magic: As its name implies, anything tangible that we can see, hear, feel, taste or touch. There are many ways in which tangible magic exists. Those born in the magical realm are blessed with magic flowing through their blood and grants them extraordinary gifts.
Elemental magic: A form of intangible magic. The gems and stones that are harvested in the magical realm contain various magics that can be utilized by anyone whether they themselves possess magic or not.
Intangible magic: Powers of the mind. Other than a few select creatures who may possess telepathy or superficial empathy, intangible magic is rare and not much is known about it.
Rune magic: Can be utilized by anyone who has tangible magic running through their blood. Runes can affect tangible and intangible magic in various ways, but they cannot affect innate magic.
Dark magic is the corruption of any of the previous magics. Anyone who uses any form of magic to bring about harm, imbalance or destruction will be infected permanently, and their souls are damned. When they are eventually caught or die, they will be banished to Mokor where they will forever never know happiness, satiety or pleasure. The soul eventually withers away into demon hood. If a demon escapes the realm of Mokor…well The Gods help us all.
