original passage: Ancient Egyptian demons can be divided into two classes: "guardians" and "wanderers." "Guardians" are tied to a specific place; their demonic activity is topographically defined and their function can be benevolent towards those who have the secret knowledge to face them. Demons protecting the underworld may prevent human souls from entering paradise. Only by knowing right charms is the deceased able to enter the "Halls of Osiris". Here, the aggressive nature of the guardian demons is motivated by the need to protect their abodes and not by their evil essence. Accordingly, demons guarded sacred places or the gates to the netherworld. During the Ptolemaic and Roman period, the guardians shifted towards the role of Genius loci and they were the focus of local and private cults.
