After looking at the empty ceiling for a few moments, Toz closed his eyes. Since he couldn't use his mana, most of his strength as a mage was gone. Since he couldn't use mana at all, he couldn't tell if his surroundings were enchanted or whether his chains were purely restraining his body. He still had his physical senses, but in the isolated cube, he only heard the sound of his clothes brushing against the ground, his breath, and his beating heart.
Toz had only tried to move his mana as usual while trying to get rid of the chains. But now that he had already distracted his own thoughts as much as possible, he had to find a way to avoid thinking about the more ominous outcomes of the meeting with the delegation from the Alliance of Kingdoms.
