Our term for the hybrid Vampires who are Sanguine & Psy.
For the most part, it's a well-balanced energy manifestation between the Psy & Sanguine; some are darker, some are lighter. If you are someone who enjoys the company of Vampires then you'll find Muddled-Blood Vampires offer a unique energy that can only be found with one that is Muddled.
Like any entity each will have to be taken on its own merit for its manifestations & bonding. They have a unique blend of skills & energy that make them a well-rounded Vampiric companion.
