My story is set a few hundred thousand years after the first vampire was made. No new vampire knows how they started, only they were turned by a vampire. Those old vampires would get killed off (eventually), leaving a new generation, the cycle continues on.
Now, I want to try and have the vampire origins start by a vampire going to the past to create the first but that presents me with a few confusing paradoxes I want to get past for a Stable Time Loop.
The transformation is through venom so the logical choice would be to bite a human and leave them to turn, thus creating the vampire cycle to start with but could potentially lead to the Grandfather Paradox due to the venom side of the transformation or does the genetic diversity of each vampire between the first vampire and the Traveler!Vampire changes the paradox?
I have considered the 'venom' to be manufactured separately from the vampire itself but using the study of the original venom but I don't know if that establishes the time loop from a Bootstrap Paradox.
