Sinestro Corps Ring

Willpower this, Compassion that......love? Those other corps have it all wrong. Constant vigilance and power shall keep this galaxy in check. Fear will hold them all in line. Fear of what's out there, fear of what happens if they disobey. It was fear that kept those bald gremlins on Oa and for a time peace was relatively kept. They understood the power fear controlled and well, feared it. I will make no such mistake. My purpose is clear. He called to me and I shall rise up to the task at hand. This ring came to me through the void because we are so very much alike.

You want this ring? Like I'd sell it to you. You would just 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.

In blackest day, in brightest night, Beware your fears made into light Let those who try to stop what's right, Burn like his power, Sinestro's might!
