Maat is an existence which all Cryptids, gods and mankind should obey, since nothing can avoid the truth of justice. The mere fact that Maat is considered as a goddess is just a speculation.
Maat was the Egyptian personification of truth and justice. She was the goddess that regulated the stars, seasons, and the actions of both mortals and deities. It was she who set the order of the universe from chaos at the moment of creation.
