Perhaps the most mysterious mystery of all in the Revengerists Omniverse , many have tried and failed in unraveling this enigma. Who is updog? Where is updog? When is updog? How is updog?  Where did it come from? What does it do? What does it mean!? Each question only brings more questions, and no more understanding than before. Nothing but dead-ends in a labyrinth of darkness.
