Adrien yelped, but his mentor moved quickly and precisely; it took Adrien a moment to realize that Valerion had seized the fireball with his hand, and was now calmly holding it within his closed fist - a few little flames escaped from the space between his fingers.

"You must be more careful", Valerion commented with a smile, still perfectly calm. "Always be mindful of your surroundings".

Adrien said nothing, overcome by awe by what he had just witnessed; then he mumbled a "yes -- sorry", and grasped on his staff again.

"It's alright. Shall we continue?", Valerion said.

"Yes -- yes, of course".

Valerion gestured at the basket; now two paper balls were flying towards Adrien - who breathed in and drew his arc. This time, a wall of light appeared to block the attack. Adrien lifted the staff from the floor, then breathed out. "Good, good", Valerion commented.
