Mirror Guardian

Dealing with Katastrophis is a huge problem that if not properly handled could potentially end life not just on our planet but in our galaxy and probably in our dimension. There's a reason that the Amulet of Mirrors is handed down from generation to generation to ensure that there will always be someone with the required skillset to handle this very unique, very difficult, and very dangerous problem.
  It doesn't really matter that the bearer of the amulet is kind of locked into the position for this to be a major title in the world, because whoever it is will step up or else they won't and we'll all die.
  Now that this has been an issue for our world, and Evelyn Suthmeer stepped up to save the world, the position of Mirror Guardian was created for her.
  It's not really a superhero pseudonym in this particular instance, although it does serve as such. It's meant to be an honorary thing that allows the various nations of the world to give accolades to someone who deserves it, and for serving a very unique role in the world.
  There's probably only going to be one Mirror Guardian ever.
  It's obviously a new creation, since the event that triggered it only just happened. It was acknowledged as including certain privileges by the various world leaders who created it in the first place. The Mirror Guardian essentially has diplomatic immunity from everywhere, and eternal dinner rights at any government table.
  There's no money associated with the position, just a lot of prestige and goodwill.
  The "mirror" part comes from how Katastrophis is a multidimensional being.
