The Zeroth Dimension, also known as Death, is the location that all Conniving Puffin Characters go when they die. It is one level lower than deep limbo. What does it appear like? Limbo's colour inverse. Pitch blackness. Death is located on the edge of the universe. The very edge of the space-time continuum. Heaven and Hell used to be things, but when alchemy came into play, all souls were sent to be tortured endlessly at the black, blank, edge of the universe.
It is the scariest place in the universe... It has lighting always striking around it... Take one good look at this image next to this text. Screaming people are heard throughout it... It's horrific.
At the beginning of season five, only Marina, David, Jamison, and Charles are there. But by the end? It zooms out to reveal that there are a lot more dead people in Conniving Puffin. There is a very ominously eerie smiling woman watching over the 0th dimension in sadistic approval, hiding in the shadows. Her name is Ms. Finch. She is a torturing mastermind, but was beaten down by Ginger when she was distracted.
