For instance, in Greek mythology, the Cerberus protects the underworld, preventing the dead from escaping. In Egyptian mythology, Ammit serves to devour souls unworthy of the afterlife. These guardians symbolize the transition between realms, highlighting themes of protection, transition, and the often perilous journey of heroes or souls navigating through their respective mythologies.
