Awakened to an endless night, vampires hunger for the life they have lost and sate that hunger by drinking the blood of the living. Vampires abhor sunlight, for its touch burns them. They never cast shadows or reflections, and any vampire wishing to move unnoticed among the living keeps to the darkness and far from reflective surfaces.
Dark Desires. Whether or not a vampire retains any memories from its former life, its emotional attachments wither as once-pure feelings become twisted by undeath. Love turns into hungry obsession, while friendship becomes bitter jealousy. In place of emotion, vampires pursue physical symbols of what they crave, so that a vampire seeking love might fixate on a young beauty. A child might become an object of fascination for a vampire obsessed with youth and potential. Others surround themselves with art, books, or sinister items such as torture devices or trophies from creatures they have killed.
Born from Death. Most of a vampire's victims become vampire spawn—ravenous creatures with a vampire's hunger for blood, but under the control of the vampire that created them. If a true vampire allows a spawn to draw blood from its own body, the spawn transforms into a true vampire no longer under its master's control. Few vampires are willing to relinquish their control in this manner. Vampire spawn become free-willed when their creator dies.
Chained to the Grave. Every vampire remains bound to its coffin, crypt, or grave site, where it must rest by day. If a vampire didn't receive a formal burial, it must lie beneath a foot of earth at the place of its transition to undeath. A vampire can move its place of burial by transporting its coffin or a significant amount of grave dirt to another location. Some vampires set up multiple resting places this way.
Undead Nature. Neither a vampire nor a vampire spawn requires air.
