Here’s one for Demon: the Descent. The player characters are a Ring of Demons who have come to the city on hearing rumors of the existence of a particularly powerful artifact of the God-Machine. Nobody is certain of what it looks like, or how it functions, but everyone knows what it is: A “Get Out of Hell, Free” card, a back-door into the God-Machine without being disassembled or destroyed in the process.
No strings, just an instant ticket for reunification with the God-Machine. Needless to say this has gotten Demons of all Agendas and Agencies looking into it. If they’re lucky, it’s only a rumor. However, if it’s not, it could be a very powerful weapon.
The Integrators are the most obvious Demons to be looking for it, but the Saboteurs think that if they get their hands on it, they can fashion it into a weapon. The inquisitors want to make sure that they know who has it, and the Guardians want to make sure that the status quo remains.
Is it a ploy by the Angels to draw the Demons in, or is it a real loophole that the Demons could use to change the God-Machine forever?
