The Spirit Realm (also known as The Spirit World) is an incorporeal dimension parallel to the physical plane of Eternia where Spirits and other supernatural creatures reside.
There are only a few known methods to enter the Spirit Realm, with one of them being the use of Rift Magic, a ritual that allows those involved to astral prospect as spirits, entering the lifestream and passing into the Spirit World. However, leaving the Spirit Realm is considerably easier - it is commonplace for wandering spirits to enter the physical world.
Characteristics
The Spirit Realm operates on a different set of rules than the physical world. The world is seemingly infinite in every direction, geographies vary radically and often morph on whim, and gravity is not always constant. A common sight in the Spirit Realm is the physical manifest of the lifestream in the form of tangible, spiraling streams of energy gliding around landscapes and horizons. Stars may be identified by locating points of great spiritual energy, often where points in the lifestream intersect.
The realm is populated by both humanoid and non-humanoid spirits. Human spirits are usually spectral images of bygone souls, bound to the physical world by unresolved strife or internal anguish.
Spirits
There are many different types of spirits that reside in the Spirit World, and these include:
Essence
An essence is a piece of a human's soul, a wandering spirit that's not yet ready to move on. They spend time in the Spirit World resolving their regrets, or return to the living realm. Some spirits will wander for thousands of years before rejoining their soul.
