For many centuries, the ''phi song neng'' (vampires who have vowed never to drink human blood) have lived among the villages of the Far East. One day over 800 years ago, a young human warlord named Niran fell in love with one of the ''song neng'', a woman named Sang. Niran wanted Sang for his own, so he killed her husband and son. In her pain and rage, Sang attacked and bit Niran during a Songkran (New Year) solar eclipse, turning him into a vampire.
