The Nog Panopticon was a non-aligned panopticon that was an ally of the protagonist's own during the story of the game. It was referred as being a somewhat peaceful but weak panopticon. It is also the original panopticon from which Carlos works in, though he frequently visits the protagonist's panopticon.
During the story, they were invaded by the Hourai Panopticon and its allies and the 'Con was destroyed, as the reinforcements sent by the Protagonist's Panopticon were intercepted en route due to an information leak by a mole. Elfriede suspected Carlos to be the mole because of his usual deceptive behavior but was unable to completely affirm this as he gave the alibi of having visited the remains of the Nog panopticon to pay his respects to the dead.
