Bloodlines are based on “old” World of Darkness “Pen-and-Paper” game universe by White Wolf. Due to some limitations, only 7 Camarilla clans were implemented into the videogame, but there is even more in the source material, modders are implementing them.
Lasombra is Sabbath-affiliated clan, they are some kind of elegant “social Darwinists”, who can control shadows.

I believe it’s the different types of Vampire you can be in Vampire: The Masquerade - Bloodlines.
[And possibly the rest of the RPG system that game was based on, but I’m not sure on that.]
Basically: You can choose from different types, each one having their own style and strengths/weaknesses.
Ventrue: Upper class, high society types.
Brujah: Fighers, quick to rage.
Gangrel: Also fighters, but closer to animals, loner types. Beastly.
Toreador: Artistic types. Creative. Obsessed with Beauty.
Malkavian: Freaking insane. Can see the future. [Or just crazy.]
Lasombra seems to be a modded expansion type race. Don’t know em~
The game is awesome. If you like Pen ’n Paper style RPG games/Vampire games with heavy atmosphere, and can deal with older style controls/graphics. Then try it!
