Longevity

Longevity refers to long, or in some cases, unnaturally long lifespans.

Description
Many beings possess extended longevity, usually by virtue of some supernatural trait. This can range from a 300 year average lifespan, to near immortality.

Wizards
Due to their use of magic, the essence of creation itself, wizards’ have the innate ability to heal at the idealized maximum of human potential. For example, when human bones break, there is usually a fracture or flaw left behind after it has healed. With wizards this is not the case, as their bones have almost no detectable trace of any damage after healing. This, when extrapolated to other bodily functions, delays the natural breakdown of the body for a great deal of time before old age finally makes catches up with the wizard, allowing them to live in excess of 400 years.

Scions
Scions generally possess extended longevity, if not nigh-immortality, from their immortal parentage. They have been known to live for hundreds of years, although they can be killed.

Changelings
Changelings, like all Scions, possess extended longevity by virtue of their parentage, in this case faerie parentage. Choosing to embrace their faerie nature will turn them into fully fledged faeries, whereas choosing humanity (or refusing to make a choice at all) will nonetheless provide supernatural traits, with some changelings being older than some Winter Queens.

Faeries
Faeries, due to the protection provided by their Mantles, can only be killed on Halloween, when mantles are malleable.

Outsiders
Outsiders, like faeries, cannot be killed. They can be harmed, but they cannot die.

Black Court vampires
Black Court vampires are undead, and so are not technically alive in the same sense as mortals or faeries. Nonetheless, they do not die of old age; in fact, the older they are, the stronger they become. Despite this, Black Court vampires can be killed by all of the traditional means laid out in Bram Stoker's Dracula.

White Court vampires
White Court vampires derive nigh-immortality from a symbiotic spirit called the Hunger, which is what defines them as vampires. The Hunger feeds off of life essence, usually via sexual congress, and then uses that essence to sustain itself and its host. So long as the vampire can feed, their Hunger keeps them alive indefinitely, meaning that the only way for one to die is from murder.

Red Court vampires
Red Court vampires are considered undead, and as such do not age. They are sustained by the blood they feed upon, which is stored in fleshy sacs called blood reservoirs.

Half vampires
Half vampires are mortals who have received the blood thirst from a Red Court vampire, but have not yet given in and provided that thirst with the blood required to transform into a full Red Court vampire. This blood thirst, called a Predator Spirit, is able to sustain, empower, and heal its host to a partial degree, increasing their longevity by several hundred years or more. However, this spirit is sharply limited in the healing and regeneration it can provide, as it lacks sustenance.

Denarians
Denarians, those who carry a coin with a Fallen within, can draw upon the Fallen Angel’s strength. Although resilient, Denarians can still be killed by normal means; however, the Fallen’s power protect the bearer from the ravages of time, allowing them to survive indefinitely.
