Alrighty. You guys still fighting over the thought that the new Volkihar Vampires are butchering the lore?
If so, think about this.. Immortal Bloods is written by a Cyrodiil, or 'Common', Vampire. He talks about the Volkihar, correct? Well, common sense tells me that he is most likely making up lies, and stories, about the Volkihar in the book.. As for his own kind, he might be telling the truth and yet, might not... It is rly simple, and highly common, thing he is doing... He is lying about the others and trying to make it so himself, and his kind, actually looks good and powerful.. Hm.. Where did I heard that before? Um.. The Government!
Therefore, Immortal Bloods cannot be totally true lore.. This means, we had no idea how the Volkihar Vampires are like until now.. When we finally saw them... And this also means, Beth isn't butchering the Volkihar Lore..Now, about the whole 'blending in' thing.. He could be lying and saying only the Cyrodiil Vampires have it.. Or he was true but over the years, other Vampires had adapted and also gained this ability.. So therefore, I don't see any lore being butchered here...
Any questions?

While there's -technically- no flaws with this theory, are you seriously telling me THIS is how it went down in the dev room:
"Ok so next up we need to design the Volkihar. What established lore do we have on them Ken?"
"Well so far we've just produced one book, but we stated that they can freely move through ice, have frost resistance and magic, and tend to attack their prey suddenly from below frozen lakes."
"Alright then, we'll have to get to work on that. We'll have to develop ways to spawn and travel from ice, but the ice magic and resistances are easy enough."
"WAIT!!"
"Yes Todd?"
"What if we DIDN'T LISTEN TO OUR ESTABLISHED LORE AT ALL??"
"Uhhhh...why?"
"Because we'll say the author of that book was a liar. Or he never existed. Or the book was a figment of the Champion of Cyrodiil's imagination. People will love it."
"....Wouldn't it make more sense and be less deceiving for the public if we just followed the lore?"
"NO! Following the lore makes no sense at all! It makes much more sense to rewrite it constantly and keep our audience guessing, frustrated, unsure and confused, so much so that thousands of fans scream '[censored] this' and forever give up on their quest to learn the lore, deeming it a giant waste of time since we constantly rewrite it all.
They'll love it."
"Huh. Can't argue with that. Your logic is flawless."
"It'd also be logical to copy-paste the vampirism files from Oblivion into Skyrim. We're totally not doing it out of pure laziness. No, this is about artistic integrity and staying true to our lore!"
"God Todd, you're a genius! We'll get right on it."
Bull[censored]. They were just lazy. There's no excuse or story behind it. It's just developer laziness.
