Pillar of Nothingness (the Pillar) is an artifact of negation: a column planted in St. Mark’s Square during the final three days of the CFA Venice endgame, exactly where the Lion of Saint Mark stood. It does not replace the guardian but cancels it.
One is said to have existed on Earth before Terra and Antiterra were generated, and Elías drove similar pillars in other eras. It is the instrument of the millennial archenemy of Graz’zt (GRDT), now turned against the captured city. It appears during the last days of the Carnival of Venice.
