New Valencia centers on an uneasy arrangement. Xelco maintains the city of New Valencia and offers a steady supply of “hema” (synthetic blood) to Vampire citizens. Those citizens, in exchange, agree to live peacefully within the city limits. But this arrangement, along with most traditional arrangements within the city, is in decay. Hema is not enough to sustain a healthy Vampire, and Xelco is suspiciously secretive about the process by which it makes this thin and unsatisfying form of nourishment. Xelco produces several Vampire pharmaceuticals — ranging from restorative medicines to Sunset, a drug that allows Vampires to survive daylight. The company maintains a massive corporate headquarters in the city center, and rumors abound that secret research facilities are hidden elsewhere in New Valencia.
