World of Darkness is a series of tabletop role-playing games, originally created by Mark Rein-Hagen for White Wolf Publishing. It began as an annual line of five games in 1991–1995, with Vampire: The Masquerade, Werewolf: The Apocalypse, Mage: The Ascension, Wraith: The Oblivion, and Changeling: The Dreaming, along with off-shoots based on these. The series ended in 2004, and the reboot Chronicles of Darkness was launched the same year with a new line of games. In 2011, the original series was brought back, and the two have since been published concurrently.

Vampire: The Masquerade is a tabletop role-playing game created by Mark Rein-Hagen and released in 1991 by White Wolf Publishing as the first of several Storyteller System games for its World of Darkness setting line. It is set in a fictionalized "gothic-punk" version of the modern world where players assume the role of vampires, who are referred to as "Kindred." and deal with their night-to-night struggles against their own bestial natures, vampire hunters, and each other.
