Vampire: The Masquerade - Sins of the Sires is an interactive novel by Natalia Theodoridou. It is a 300,000-word game that is entirely text-based, without graphics or sound effects, and fueled by the vast, unstoppable power of your imagination. The game is set in Athens, Greece, where the Camarilla establishment and the Anarchs are at odds with each other. You are a vampire, hidden from mortal eyes, and must navigate this society and hide your true nature.

In this game, rumors spread of an ancient vampire, Aristovoros, intent on bringing about a new world for the Kindred, an end to the Masquerade. You can choose to become Clan Tremere, Ventrue, Malkavian, Banu Haqim, or thin-blooded. You can play as a man, a woman, or a non-binary person, femme, masc, or androgynous, and as gay, straight, bisexual, queer, or ace. You must rise within the ranks of the Camarilla, stand with the Anarchs, or forge your own path. Unmask your true sire and play your part in this game of masks.
