After the fight with the Heart of the Blazing Lion army everyone was tired, but nobody could rest soundly. There was no way that they could sleep like nothing happened.
Everyone was restless. They had felt the great power of their enemies and how big the gap in their strength had been. Clearly, the Untamed Army had been at a disadvantage. Their numbers didn't even reach one-tenth of the Heart of the Blazing Army and they didn't have a single Higher Lifeform in their rows.
Despite everyone's doubts and worries, Michael decided that everyone should rest a little bit.
He wasn't ready to rush his people from one major battle to the next. That would cause more harm than good.
