The setting is Earth: 2070. No reasonable human being believes in vampires. All those B-movies and trashy romance novels really did wonders for vamps in that regard. Nowadays any supernatural feats they might be seen/filmed doing are easier to attribute to something else. (Black market cyberware, hyper-PCP, illegal gene-mods etc.) Too many agendas and conspiracies discrediting the supernatural for any but those behind them to believe in vamps.
