Origin
Did you ever think of where mortals, vampires and gods came from? Here's the explanation.
~*~
Mortals evolved from apes, as the scientists say. humans are mortals and a few can become an immortal as a version of the undead but not very many. the only vampires I know of right now this very minute are Lestat and the group of vampires who survived the war with Queen Akasha. The hemoglobin factor also helps with the classification. Humans have a lot of hemoglobin.
Vampires are humans but they are vampires because of the low hemoglobin count. If you watch Blade it'll explain the vampiric hemoglobin count of the vampire kind. As you probably already know the older a vampire gets the more powerful and less the hemoglobin count. As they get older they become more god like and develop certain traits like sun walking and things of that nature. then when their old enough, they become gods.
Gods are really, really old vampires. Gods have no hemoglobin count and without that they don't age or anything. Gods grow older and they don't die. that's why their gods.
~*~
To sum this all up, if a mortal, or human, gets bitten by a relatively young vampire they become one. If they stay alive long enough they eventually evolve into gods and evolve form there. but the evolution from bloodsucker to god like being takes millions of years. Evolution is the key factor here. Time is the key factor here. Don't worry, if your evil enough one of the immortal things will happen. Flaunt your evilness and willingness to die. then maybe you'll be chosen. Pull a Louie and watch the shadows.
I did.
