Kyran did not know how to respond to that. But one thing he knew was that his body started to feel strange after the tension from earlier abated.
No.
That was not entirely correct. It was after he used the Void Domain that the strange feeling in his body appeared.
In other people's eyes, Kyran's defiant attitude toward the Dragon Emperor lessened because he was too focused on maintaining his domain. When Kyran summoned his domain, his primary target was Cyneah, with the Dragon Emperor as secondary only. But because the latter possessed far greater magic energy and mage level, maintaining the domain took a lot of toll on Kyran's mind and body. He also had to be careful not to alert the Macabre Glacier's sentient of Shaiha's presence.
