Adrien gasped. "I know -- I know I should, but -- it just seems so --".

"I understand that it looks dangerous, but, really, don't worry: I repeat - you are safe in this tower", Valerion said with a soothing smile.

"Alright. I'm sorry", Adrien said, sheepish.

"Don't worry; you are doing amazingly. Would you like to try that again?".

Adrien smiled and nodded. Another paper ball flew towards him; he drew an arc and thought of the fireball. He saw the fireball fly and engulf the paper ball; he planted his feet on the ground and stared through the paper ball as it burned in front of him. This time, the fireball fully consumed the paper ball in mid-air; he watched the ashes fall just past the glowing border of his spell, then he lifted the staff from the floor and breathed out. "I think I did it", Adrien said with a smile.

"Yes, you did", Valerion nodded. "Well done - well done, Adrien".

"Thank you", Adrien chuckled. "How strange -- making a fireball was easier than standing still in front of it".
