Immortality

Immortality can be broken up into some distinctions. However due to the nature of Immortality beings that are immortal usually out live their counterparts this tends to either make the being view life as worthless, creates great dissatisfaction, or traumatized the being. The exception to this comes from immortals who live within a group of another immortals. As such immortals tend to live together to fulfill their social needs.

Eternal Youth
Eternal Youth is a type of immortality in which the being does not age but is still able to be killed through unnatural means. A good example of an eternally youth being would be a Fallen Angels as they will not die of old age but can be killed.

Forced Rebirth
Forced birth is another type of immortality that is done by forcing one's soul to either take over a host or reincarnate. You can transferred your conscience into another being thus your soul will begin take over it's body. If the being still has it's own soul the two soul with fight for control until one erased the other from existence. Forced reincarnation requires you to condense your soul so that your conscience remains after death, this will result in either being born in a new, or materialize as your original form depending on the level of compression. The cycle of Angels is an example of forced reincarnation as Angels are condense souls from birth.

Divinity
True Divinity is more accurately described as Aethereal bounded, a state in which a being's soul is bound to the Aether. Most obtain this state through effort. Demon Lords force their wills into the Aether and Druids form pacts with Aethereal Beings. However some beings are born like this, Vampire Progenitors and Deities being such examples. Although all that obtain Divinity can be called Deities, natural Deities are rare and cannot be classed as anything but. All beings that have a presence in Aether can be revived should they died, unless someone destroys their point in the Aether. the Their are also those that claim Divinity but don't actually have a presence in the Aether, this are know as Fake Deities and is extremely offensive whether if be correct or not.

Demi-Deities
Demi-Deities are beings that are born of partial divinity, not to be confused with the offspring of two deities. While they do not have as large a presence in the Aether as proper Deities they are still in essence immortal. They can be resurrected and have immense strength but do not hold up against an actual Deity. When a Demi-Deity has it's own offspring the gift of the Aether is not passed down any farther, thus the child will be underwhelming.
