Green Lantern Ring Variant

So, I found this ring, not sure what it does, but it looks pretty cool. It's green, I think it may have belonged to someone special. All I know is, I put it on the other day and crazy stuff started happening. I could fly, got a cool space suit and could make all sorts of neat stuff,....never experienced anything like that before! But then these floating space dudes told me I had to protect the galaxy or something and that was enough for me!

I'll sell it to you, but don't come running back if things get out of control or if you feel crazy superpowers.
(note: Doesn't actually grant super powers, but it would be cool if it did)
Inspired by the green lantern comics by DC. This ring is circular in shape.

In brightest day, in blackest night, No evil shall escape my sight. Let those who worship evil's might, Beware my power... Green Lantern's light!
