Immortality

Immortality is a concept that comes up for several races in the game. These include gods, dieties, and some lesser races.

Background
Immortality general means living forever with immunity to disease, aging, and natural forms of death. This doesn't mean they can't age, as is the case with Manannan, but that aging will not kill the immortal being. This however doesn't mean that 'immortals' are immune to death, as their physical bodies may be prone to death through magical wounds, or other means. So immortality shouldn't be considered 'invulnerability'.

Immortality can be conferred on mortal individuals through magic, magical fruit, or other means. Though this is usually rare.

Some forms of 'immortality' may exist with 'undeath', as is the case with vampires. But depending on the form of undeath, some undead are still prone to decomposition in time. Vampires however tend to be more resilient, and potentially regenerating form injuries.
