Humans are a race of mortal, sentient beings who are members of the species "Homo Sapiens". Humans serve both as a food source as well as a means of pro-creation for vampires, who reproduce by performing a ritual that will transform a human being into an undead immortal. Humans make up for the majority of the earth's population, and are commonly noted for their desire to influence and understand the environment by seeking to explain and manipulate phenomena through mythology, philosophy, religion, and science.
