The question a reader asked about Immortals. I am not sure, but I believe I answered this question some time ago.
According to the ancient legend, a true immortal can not be die nor be killed. At least not by a humans or other immortals. Anything that can be killed by a human is not an immortal. An immortal means ‘one who can not die.’
In all ancient myths, legends or whatever it is called in that particular culture. Only the creator of all things can kill a true immortal.
Vampires, werewolves and such monsters are not immortals. Fairies are. Demi fairies are not immortal. They are a Nephilim. They can be killed. According to some ancient texts vampires and werewolves are a form of Nephilim.
In other cultures they are a form of revenant. No, not zombies. Again, meaning they can be destroyed.
With a revenant an immortal has reconstructed and is indwelling in that body as to why it doesn’t perish. A zombie, a demon has animated it as to why it perish.
Zeus, Odin, Jupiter, Wolden, Juno, Quetzalcoatl, Van, Lugh, are all immortals.
Vampires, werewolves, cthulu are not.
I don’t write by the modern definition of what these beings are. I stick to the original text. 🙂
I hope this answers your question.
