...A Ring to control the others? Good idea. Let's just hope that doesn't get stolen and/or destroyed...But just in case, let's pick rings with powers that we do not want the baddies getting at-particuarily stuff that's too powerful, or stuff that's too...Good-sounding. The former makes them a helluva lot stronger, the latter gives them good publicity which WE DON'T WANT TO DEAL WITH!

...Oh, yes. Silveos, you may not have KNOWN this, but Physical attacks-IE, me using the Universe Edge on your face-are totally different from Energetical and/or magical attacks-IE, me using magic to freeze your pants off. I would take note that there aren't any rings that protect against the latter...Trust me. Just, just trust me.
