After the Dawning, when spirits were forced to find refuge from the Sun, many of them bound themselves to living organisms, including men. This process imbued the possessors of these spirits with unusual powers and features. These spirits then followed the bloodlines of men, passing to offspring, creating strains of humans known collectively as the Blooded. There are three principle divisions of Blooded:
The Lightblooded possess the spirits associated with goodness and light, though the individuals possessing these spirits may exhibit none of their spirit's good-nature.
The Darkblooded often possess spirits of murder, violence, and other predatory instincts.
The Strangeblooded possess spirits of unknown or indeterminate natures. Their powers are far ranging and unpredictable.
