Valerian was unaware of everything that was going on outside in the main hall, he was focused on his meditation, suddenly, something clicked in his mind and he channeled mana through his eyes, then began to sense where the mana was stored. The sensation of mana channeling through his eyes was different and he could remember. 

Focusing on his senses, he probed his entire body to find this sensation. However, the effect was not good. With the result of his search turned up empty, he became depressed. However, he understood that it would not be a piece of cake to locate the mana storage in his body. As he was contemplating time passed away and after two hours, just as the maiden had said, Trin appeared at the door and woke him up, "Master Valerian, it is about time we leave."
