Werewolf-Vampire Hybrids

Mystic Investigations has never run across a Vampire-Werewolf Hybrid but there are ancient anecdotes of such entities existing. It seems they could hold the same power as their vampire sire and possibly even the generation above that of a sire. This potentially means a First Generation Royal Vampire created Hybrid would be as powerful as a Demi-Demon! If they still exist then they are quite rare. They are sometimes referred to as Vaewolf, Vampwolves or Wolfpires....
