Most vampires are more or less the same, save for a few differences depending on the region. Vampires of Daggerfall may not enter holy places, for example. Morrowind has three different clans of vampires that specialize in magic, stealth, and strength. I myself am a vampire of Cyrodiil. This means I have certain powers.

I have heard of taverns that serve blood, and some places even give bags of blood.
