The mortal vampires are called Moroi. The Moroi don't have those problems like story-book vampires do. Yes, they need blood and they don't like the sun - it makes them a bit faint - but otherwise, they're normal people with a few quirks, not the most physically strong and they have magic.

Dhampirs don't have any of the Moroi drawbacks, but we also don't get the magic. We're really fast and strong, but that's about it.
