Werewolves and Vampires. Not VS
Unsure of what the actual title should be when I go to make the OOC.
Anyway, my idea for the werewolves is they are like you're normal everyday werewolf, but with a hidden ability which can only be seen in his/her werewolf form. Changing at will or changing on certain conditions is up to you.
Vampires who were once human themselves. However, they have been turned into a vampire like usual, but demonic vamps also have this ability to inherit demons into the human that they bit. Once bitten, you must go through the vampire phase first. The demon will need time to develop before it is ready to be unleashed(only time will for this part of it).
