Welcome to Las Vegas
John Anastas and Giovanni la Figlio stole an old family bible from an auction after learning ot was an artifact of some power. After stealing it, they learned that it was cursed; the present owner can’t get rid of until he or she is killed and everything he or she cares about is destroyed. With the help of Mark Eden, who detected that the bible was possessed by some sort of powerful malignant spirit, they eventually bound the bible in several layers of nested boxes covered with magical sigils drawn by Mark; the curse hasn’t been removed, but it is at least temporarily neutralized.
In the first session, a mysterious caller calls to buy a copper ring disc that is embedded in the back cover of the bible. They find the murder (plus his bodyguard and four security guards) murdered by two mysterious killers and are propelled into a dangerous mystery.
