Can it be replicated, because that's key from a genre perspective.MTG has the Silex, an artifact that when activated can decimate or even erradicate a plane. The strength of the blast depends on the user, and can go from nuking a small island to a huge explosion that causes a nuclear winter.Specifically the user pours all of their emotions and experiences on it, the more intense the stronger the explosion.
That's interesting. What's the mechanism for making rings of wishes such that the information can be stolen?
EDIT: What's extra interesting about this is if the wishes aren't restricted to being destructive. A cold war of people trying to stop their rivals from creating a better/perfect world is a neat idea.
I kind of like that temptation though. Sure, your mission is to kill the efreet and stop the production of the ring, but you could also let it go forward and then steal it so you can wish your dead spouse back to life..The mechanism/secret could simply be the ritual for binding a powerful efreet to the Ring (which is what gives the Ring its power, and which also explains why the wishes tend to go wrong/destructive, because a bound efreet it not a happy efreet!). Once you know the ritual (the bomb schematics) you can copy it and repeat it many times, but each time, you need a new efreet to act as payload (the plutonium)
You would of course also have a flourishing black market/espionage industry in old tomes, research etc that will yield the True Names of suitably potent efreet to be bound by the ritual. And of course the efreet themselves might get involved, vengefully for anyone who tries to bind them, or sneakily if it might be useful to let slip a rivals True Name to a ringmaker.
I think the reason i suggested that the wishes could only be destructive was to keep the Cold War vibe, but also because it eliminates a bunch of temptation on behalf of the individual engineers, spies, middlemen etc in the process to just turf all the spying business and just wish themselves a long happy life on Bikini Model Island if they ever get their hands on a ring. If all a ring can do is destroy, its utility to fulfil individual desires is limited.
