It is a bit interesting to see some of the discussions as a person who has no knowledge of these other properties.
Granting that what we are referencing is the primary source that Likesblondes is using as a template for his vampires, getting into this lore is actually a great deal of fun. I have saved the four slots we can have to transition from Rebirth 1 to Rebirth 2. In them I have 2 that I made charisma based, but only one was on purpose, the other was more or less luck. Both of these were successful, but only 1 of those 2 has all three powers unlocked. I then did the prowess route which is arguably the easiest to open all three paths on, and I unlocked all 3 powers. The last one I finished this morning was the stealth based one. I had a hard time getting to the Whisper power on previous stealth attempts, however I nailed all 3 of the paths this time through.
While I know that either the moderator(s) or perhaps the developer frowns on referencing the inspirational material, I have found a lot of hours of enjoyment of speculation of who is what in this wonderful AVN.
One thing that I feel I have to place into my comments frequently is that as we are on a pirate porn site, the expectations of the viewers needs to be managed. Not for my own ego or anything, but because I absolutely respect the work of the developer and do not want johnny come haters to come along complaining about not having much animation or renders of actual traditional sex.
The MC is hung up on sex because he is a brand new vampire and doesn't at first realize that his world has suddenly become so much more expansive and different, and those who play this AVN may not realize this at all as well.
Sex is not a thing for vampires. It does not have the same psychological or physiological effect on vampires that it did for humans, or would for thralls. In fact, for thralls, who have had their world altered, sex would become another addiction for them to express their devotion to their domitor. EXCEPT, the domitor could care less.
