Idea:
In a moment of need, most people from Clementia gain powers that help the, with that specific problem, and go away once that problem is solved. Some people, though, called the Forsaken, are born with less Investiture than average. Some of the people who do have the magic were granted the power to help the Forsaken, and they are called the Merciful. As such, the Arcana on Clementia can take a variety of different forms. The exact specifics of each person’s magic is determined by Mercy’s vessel, Prinil.
