Metahumans or Menace?!
Tartarus is the equivalent of the deepest darkest dungeon with the most unimaginable horrors existance has to offer. And it’s exit is broken. And the entrance is controlled by Andrew Vulcan’s Uncle. It is a 9 days fall from the underworld. And only the most dangerous and evil beings with no hope of redemption are cast down to it’s depths. It holds horrible, ancient monsters and of course, the Titans.
