The Pact

From the introduction: The Pact is a game for two players. The players were best friends as children, and at some point, made a promise to each other, like children do, that if one of them was ever turned into a vampire that they would turn the other one into a vampire as well, so that they could be best friends together forever. At the time, both children knew that vampires didn’t really exist, of course, so after a while the promise was forgotten as juvenile fancy, and there would be no further talk of vampires as they grew up together.
