Training II
The true form of mana is formless, shapeless, colorless, odorless and invisible. It's not there but yet it is, sensed but not seen, felt but not touched. Inhaled but not smelt, heard but without sound, enticing but without scent. Mana can appear and be understood by anybody based on their perception of it, and no two individuals are the same when it comes to the ability of sensing mana. For Asd he had to understand what Mana is, which he already did, the amount of time he spent at the academy could not have been for nothing, it was a crazy endeavor what he was about to do, and even more so the fact that he was doing it underwater.
