With this magic ring, the wearer can see far and distant places.
I was thinking of the ring in LOTR that allows the wearer to be invisible, but also unfortunately draws Sauron closer. Pictured here is Shark Fin Cove under the moonlight and Milky Way. In LOTR they actually had seeing stones, but I think a ring would be handy too ! Middle Earth wearable tech ? 🙂
