So while listening absentmindedly to BR at work, I got to the part where Eb showed up with his pickup truck to pick up Harry and take him to pick up Murphy. Harry made mention of Eb's rings on his index fingers. That made me think of all the times we have had references to rings of power in the stories. We have Molly making Harry one in PT, Harry's force rings, Elaine's shield ring, Mab's present to Maggie, and Eb's rings which I like to believe he holds his fingers like a gun, index finger pointing, and mimics pulling the trigger to get pinpoint accuracy with a force blast. But alas, we don't have any idea what his rings actually do, just ideas because of being Harry's mentor and grandfather.
So the fun idea comes in here.
Say Harry is going to get married for real. To someone who has magic (Molly, Elaine, Luccio). And say that he makes the ring himself. What do you think he does to the ring? Locator beacon, force ring, shield ring, something else entirely?
Thoughts?
I kinda think it would have a beacon to it so Harry would always know where the person is and it would stay active while the person was alive or had been taken off, being powered by the persons energy.
