I'm really liking these indepth Vampire discussions

even though I haven't a clue o_o How do we know these are Skyrim's own breed, I mean we know there are this order and this Volkihar, have Bethesda said the Vampires are one or the other? Just asking really, I don't go too far into lore or sorts, and I have little interest in Vampires.
If Bethesda said something, we really wouldn't have a discussion about it

. But sadly, they didn't elaborate on vampirism and it's clan. They have little covens such as Alva's coven of vampires, but they are most likely based on a single bloodline. Movarth Piquine was bitten by a Cyrodiilic vampire, he's mentioned in the book "Immortal Blood" in Oblivion and in Skyrim, and he's featured in the game. So it made me raise an eyebrow. We have a mixture of vampires with powers that are different and the same. Bethesda just said "Screw lore, let's just copy and paste the vampirism and add new things, contrary to lore."
Know what I say? Just say the Order began comingling with other less barbaric vampires from Skyrim or something. Problem solved.
Indeed it's odd, and a more concrete statement of why it's so would be nice, but all we're left with are guesses and assumptions. My friend figured it's just because the Nords of Skyrim are generally simpletons that if you feed before becoming Blood-Starved, they just assume you're sick or something. And while that makes sense, it's also kind of a kick to the player's shins. Or they're just figuring that 200 years is a really long time so that some/most/all of the lore before that is null. Which is pretty "wait, what?".
I agree entirely, it's annoying. In Oblivion it was more or less the same thing. The more you went without feeding, the more people said you were sick. The fourth stage, people realized you were a vampire and chose to shun you. The more people you talk to as a blood-starved vampire in Oblivion, the more chances you will get attacked by guards.
I broke into a house in Oblivion, and the guard went and attacked me, saying "Feeding time is over vampire. Go back to the grave that spawned you."
So not even a "go to jail" choice was given. In any case, it's the same thing. Feed on sleeping people, look more human, less problems in the sun.
