ARGH, dude? Are you seriously that dense? The world you see in-game is a limited version of the wider, broader, much larger world today's video game technology is not able to present to you.
There is not just one book. There are many. There is not just one source. There's a whole world. Farms are not the size of your backyard vegetable garden. Etc. etc. etc.
I think you're missing the point entirely. This thread is about Volkihar vampires, not a debate on game size. If you want that, there are plenty of threads already on the subject.
Snake is not dense for saying there is no example of the Volkihars abilities. Hell, I didn't even know there was such thing as a Volkihar vampire until this thread was posted.
