Valerion burst into laughter. "If you can imagine the water dragon clearly, then yes - but that would be a bit excessive for a fireball, don't you think?".

Adrien giggled, his fingertips against his lips to hide his mouth. "Maybe it's a very small dragon?", he said between one chuckle and another.

Valerion laughed. "Personally, I would say to avoid disturbing a dragon of any size unless you have a good reason to - but this is just my personal opinion. I suppose that if you can imagine a dragon with ease, then please, by any means, conjure every dragon you can", he said with a light chuckle. "The most important thing is that you should find a thought that you can easily grasp and hold on to. The learning of magic is, first and foremost, a journey of self-discovery... As trite as it might sound, it is the truth. To understand magic, you must first understand yourself - the way you think, the way you are; which frames of thought resonate with you the most, which concepts align with your way of experiencing the world. To gain this understanding is one of the goals of your apprenticeship here".
