The Barbarois
A clan of creatures that has served the purposes of the people of the night for 5,000 years. They seem to be led by some freaky old guy that rides around on a unicycle. They are the group that is hired by Carmilla and/or Meier (Not 100% sure) for $100 million to protect Meier on his journey to the city of the stars. The old guy tells D that if D offered more than $100 million maybe the Barbarois would let him live. The Barbarois don't really back down on their deals so he wasn't really serious and D probably wouldn't have paid him anyway. So D ends up killin a few Barbarois and then with that wonderful distraction set up by the Marcus Brothers D is able to pass through the Barbarois city / lair / dungeon place. You can tell this is real official information lol.
