Aura

"Boy... I know you're curious about my aura." The elder says surprising, and scaring Sam. "How? How did you know?" Sam asks sweating bullets.

"Why it is simple. Your aura gives you away." The Elder replies in a matter of fact tone. "What is aura?" Sam asks. "Simple. It is your presence. Your very being." The Elder answers.

"Why don't i see mine?" Sam questions. "Simple, you're too weak." The Elder answers sending shivers down Sam's spine, he was one of the strongest in the kingdom, just what monster is this 'Elder'.

"Ha Ha, you have no idea how powerful the demon king truly is." The Elder remarks. "Is he stronger than the other kings?" Sam asks. "Yes... Far stronger!" The Elder replies.

"Then. Can you teach me!" Sam asks. "Why; You are my prince." The Elder answers.

...

"Ahhh!" Sam grunts while falling onto the hard floor. "HA! Ha, i know, i know, but this is the only way, 600 pushups, 600 sit ups, 600 squats, 6km run! Everyday in tell you feel your blood boil with aura, in tell then, AND ONLY then, will we begin your training!" The Elder says.
