Sealed Planes

The Sealed Planes are a collection of planes of existence, each home to an Elder God. All of the Sealed Planes were created by Neket at the end of the First Era.

Background
During the First Era, the Elder Gods used the races of the world (and other gods) to fight proxy battles for them. Neket, the Elder God of Order, saw this, and believed that these wars would continually escalate in power until they resulted in the destruction of Somara itself. After creating the Outer Planes, the Inner Planes, and the Astral Sea, he sacrificed a portion of his own divinity to create the Sealed Planes.

Each Elder God was imprisoned within their own Sealed Plane, molded and shaped to their liking. Each Elder God holds supreme power over their own plane, but are unable to leave it. In addition, no mortal creature would be able to enter these planes.

Because nothing would ever be able to enter or exit these planes, they were collectively referred to as the Sealed Planes.

The Breach in the Seal
In theory, nothing is able to get in or out of the Sealed Planes. However, there appears to be some way around this, as most the Elder Gods have either appeared to mortals, shown them parts of their plane, or allowed them to enter the plane itself. The loophole they use to escape Neket's divine orders is unknown, but it has been the source of many warlock pacts under the Pact of the Great Old One.

Facerum
Facerum is home to Valazar, Elder God of Creation. Facerum is an ever-shifting plane of creation, continually building upon itself in every direction. As a result, every mortal who has claimed to have visited the plane reports wildly conflicting descriptions.

Nothing built in Facerum can ever be destroyed, and nothing ever decays. As a result, creatures do not need to eat or sleep, and they do not age.

Facerum is said to be inhabited by monstrous creations that continually grow new limbs, appendages, and organs.

Morta
Morta is the home of Guul, Elder God of Death. Morta is bleak plane, with infinite gray skies above a drab wasteland. What passes for vegetation seems to be on the verge of death, and is too brittle to be used for constructing anything useful.

No living thing can survive long on Morta; food spoils, people age more quickly than normal, and organic material decays (such as wood rotting, and iron rusting).

Morta is inhabited by only one creature: Guul himself. The few who claim to have seen Morta describe him as a massive, morbidly obese creature with vaguely humanoid creatures and sickly green skin. He wanders the wasteland, devouring anything unlucky enough to come across his path.

Luminux
Luminux is home to Talus, Elder God of Light. Luminux is a plane of perfection and beauty, in which no evil can thrive. In fact, creatures on the plane are physically unable to commit acts of evil, or even conceive of any form of evil. Any creature that is evil by nature (such as a fiend) is instantaneously destroyed if it sets foot on Luminux.

Luminux is described by many as a pure paradise. Every sensation on Luminux is enhanced in a similar manner to the Feywild, with all sensations being enhanced beyond normal levels.

Luminux never experiences night or darkness. Every surface and substance in Luminux emits some form of light. Creatures on Luminux do not have shadows.

Luminux is said to be inhabited by extremely powerful celestials, who serve both Talus and any wholly good creature that enters the plane.

New Malumbris
New Malumbris is the home of Vorokar, Elder God of Darkness. It is more or less a faithful recreation of Malumbris, a former plane which had split into the Hells and the Abyss due to wars between the fiends and celestials.

New Malumbris is said to be a plane of pure evil, and that no good creature can exist there. In addition, no light can exist there, meaning that it is nearly impossible to provide any physical description of the plane.

New Malumbris is occupied by Vorokar, as well as legions of powerful fiends that remain loyal to him.

the Far Realm
The Far Realm is home to Yfuleg, Elder God of Chaos. The Far Realm is an utterly alien place, where the natural laws of the universe do not exist. As a result, it appears different to every mortal who claims to have glimpsed it. This is often theorized to be because the mortal mind simply cannot comprehend the pure chaotic contradiction of the plane, and therefore any description is the mind's attempt to make sense of the nonsensical.

The Far Realm is home to many bizzare and alien entities. Abeloths, Beholders, and Mind Flayers (among others) are said to come from this place. In addition, many divine beings of great power exist there, collectively known as the Eldritch Beings, which often make warlock pacts under the Pact of the Great Old One.

Inatus
Inatus is Neket's own realm. It is said to be perfect and orderly, with no room for chaos.

Unfortunately, no contemporary descriptions of Inatus exist, as Neket neither attempts to leave nor allows mortals to enter/glimpse the plane.
