Green Lantern's Might!
While rummaging through my belongings, I found my Power Ring signed by no less a luminary than Green Lantern's creator, Marty Nodell. I'd bought it from this incredibly charming (and not-so-busy) gentleman decades ago at one of my infrequent forays to the pique of geek, a Comic Book Convention.
As expected, I have a Green Power Ring for I "have the ability to overcome fear" (or some such nonsense.) You can find out your Power-ring Colour if interested.
