The most well known trial, the Trial of Axía with the name stemming from the lost language of Superbian script. "I pragmatikí mou axía eínai i dýnamí mou" or my True Worth is my Power.
This is the exam that is given by all 5 named Exousia against one and their handpicked supporters from their legion. This trial is unpredictable and usually defines what the current Exousia believe to be the qualities of a True Noble. One may be powerful on their own, but if they cannot prove their worth, they will fail and failure in this trial has some kind of cost either by the one taking it or the ones supporting them and is paid in blood.
When completing this trial, one's time at Curse Academy is rendered as complete. They may choose to do as they with their time past that point or move past Curse Academy onto greater things. Very few choose to stay, but some, like a former Exousia; Lucious chose to stay after succeeding against the previous Exousia after taking the exam at the end of his first year.
