While the concept of a trinket having magical powers seems implausible in our reality, the existence of multiple realms, governed by different physical laws, makes it theoretically possible.
According to the Many-Worlds Interpretation (MWI) of quantum mechanics, every decision or event creates an alternate universe where the decision or event unfolds differently. Therefore, it is conceivable that a realm with alternate physical laws exists where mere trinkets possess extraordinary powers.
In such a realm, the fundamental forces of nature could be altered or manipulated, allowing for the manifestation of seemingly magical abilities. An object's composition, structure, or even its history might impact the local spacetime or particle interactions, unlocking new properties and capabilities. The trinket could act as a conduit or amplifier for these altered forces, enabling the wielder to access and control its extraordinary powers.
