The small bronze ring was the ring of credulity.
It granted the wearer of the ring a powerful and unique ability: the power to alter reality to accommodate what they heard and believed was true. Skeptical people tend to make little use of this ring, which always seem to find its way to more gullible people. Essentially, when someone would tell the wearer something that they accepted as true, this would become -or stay- true. Reality could adapt in subtle or grandiose ways. If someone was to tell the wearer, for example, that dinosaurs still roamed the planet somewhere secluded, and the wearer would accept that as a fact and agree, surviving dinosaur would appear in reality on some distant or hard-to-reach location. If the wearer was to call bullshit on the statement, nothing would change – if surviving dinosaur roamed into deep cave complexes or in the depths of some ocean, they would not vanish. On the other hand, if the wearer was to accept that someone says that Finland does not exist, the Scandinavian peninsula would become an island, and history would be rewritten accordingly.
The opposite effect belonged to the ring of skepticism, where the wearer had the power to reject propositions about reality and make them false, a much more chaotic and unpredictable power.
What's also important to know is that while the ring alters reality to make the wearer’s perception correct, nobody will notice the changes. Only if the wearer puts the ring on his right hand, might he notice the side-effects of the reality alteration. Usually, this takes a bit of time before they amount to something that will cause the wearer to raise an eyebrow. But more drastic changes can be discerned faster.
The ring sat there, magically calling for a naïve soul to reach for it. Whenever it was not worn, it constantly created a small spell which made it appealing, and made those nearby want to try it on.
