As Frost's consciousness struggled to stay awake during the last 45 seconds his mind drifted back to his lessons with Maya.
"Aura? It's hard to explain its intricacies. It's a personal power that is unique to each and every individual. It's your presence the literal manifestation of your strength. As you grow in strength so does this manifestation. At C-rank you can sense it and begin to coalesce it into a loose form. At B-rank you can control this loose form to enhance your body, add strength to your attacks and even intimidate others." Maya gave many lessons, and not all were physical. Sometimes she'd have to explain the logic and reasons behind his training.
Frost was a studious and hardworking student but sometimes he failed to grasp the deeper meaning within her explanations until he experienced a random moment of clarity, of enlightenment.
