Each being in Pandemonium has a unique magical signature that is attached to them which is why it is not easy to fool someone in Pandemonium. This is one of the reasons why people could easily identify bandits since every gate has a magical signature detector. Those with records of having a bounty stay far away from cities in order to not get identified.
