Final answer:
There are no definitive levels of an Aurate's loyalty as the terminology is not standard, but Devotion, Allegiance, and Fealty are concepts associated with forms of loyalty in historical contexts. Regarding Roman mystery cults, these cults are known for their hierarchical structure of initiation.
Step-by-step explanation:
The levels of an Aurate's loyalty, as mentioned in the question, seem to be a conceptual rather than a factual inquiry. The concepts of Devotion, Allegiance, and Fealty pertain to different forms of loyalty that have historically been associated with the service to a sovereign, country, or cause. While these terms are related to social and historical contexts, the precise 'levels of an Aurate's loyalty' are not standard terminology and the question seems to lack a factual basis. In a general sense, however, fealty often refers to a medieval knight's sworn loyalty to a lord, devotion is a profound emotional attachment or commitment, and allegiance is a duty of loyalty or obedience, usually to a state or sovereign.
Regarding the Roman mystery cults, an important feature was their hierarchical structure of initiation. Initiates would often start at a basic level of knowledge and commitment and progress through stages or ranks within the religious community, gaining access to more complex rituals and secrets of the faith as they advanced.
