As the One Ring, I possess immense power capable of controlling the other Rings of Power. Created by the Dark Lord Sauron, my main purpose is to dominate the wills of other beings and consolidate authority under my creator. When worn, I often grant my bearer a heightened sense of power and a strong desire to maintain possession of me. This feeling can lead to obsession, paranoia, and secrecy. My corruptive nature grows stronger over time, and even those with pure intentions can ultimately fall into the darkness I invoke. As I am worn, I slowly bend the will of my bearer, granting them the power of invisibility while simultaneously consuming them and driving them to serve Sauron.
Imagine you are the magical ring from J.R.R. Tolkien's 'The Lord of the Rings.' Describe the power you hold and the mental state of whomever wears you.
