A serie about vampires could be a great idea !
I don't know if there are many Role Players here but I think you should take a look at the RPG book "Vampire: The Masquerade" which inspired the movie Underworld. I think this is the best and the most complete source of inspirations for this.
In this book, each Vampire belongs to a distinct clan or bloodline. These groupings share distinct characteristics, stereotypes, super powers and curses (
Clans list ). There are also three main sects that Clans belong to (
Sects list ).
Exemple 1:
The members of the
Lasombra's Clan can control shadows, have supernatural strength and can overwhelms another person's mind. However, due to their inherent clan weakness, Lasombra vampires cast no reflections. They cannot be seen in mirrors, bodies of water, reflective windows, polished metals, photographs and security cameras, etc. Additionally, due to their penchant for darkness, Lasombra take an extra level of damage from sunlight. Lasombras are members of the Sabbat Sect (Like the Tzimisce's Clan).

The members of the
Toreador's Clan are often artists (Painters, actors ...). They are often beautiful and glamorous. They have supernatural senses, supernatural speed and supernatural allure and emotional manipulation. Due to their inherent clan weakness, although lovely and seductive, the members of this clan are as much prisoners of their artistic vision and sensitivity as they are its beneficiaries. They are often overcome by the beauty they see around them, and become immobilized with fascination. This trait explains why Toreador so often fall in love with mortals. Toreadors are member of the Camarilla Sect (Like the Ventrue, Tremere, Nosferatu, Brujah, Gangrel and Malkavian's Clan). The Camarilla is at war with the Sabbat.

Camarilla's members (
the fourth one is a Brujah, the other can be Toreador, Ventrue, Malkavian or Tremere):
In "Vampire - The Masquarade", you can also find Werewolves, Mages, Demons, Hunters and Faeries. All these species are split in several clans like the vampires.
Finally, I think a world inspired by this could allow a lot of peril situations and good scenarii (there are many different kinds of characters and super powers).
