The Five Rulers Trial

For me, this event means two things. One: Humans are not safe. Intelligent Non Humans are not safe around them. Growing up thinking you're human, directly exposes you to human nature. As a future leader of Fernweh, you need to be fully aware of the danger humans pose.
Two: The challenges you face, during and after discovering your true origins will shape you into a more mature individual.
At least this is how the trial is viewed.
