The armies were all exhausted from the continuous battles yesterday. Thanks to Elder Koronn, all of them were able to destroy the Luxera that have been released from the seal. They were all resting as they have wiped out each enemy that the Goddess of Light Luminaria has created.
The armies expected a fight the next day as well since more powerful Luxera have seeped out of the crack the following day. They waited in anticipation for the next wave of enemies to appear, but they were surprised that nothing came out. The armies would have been much more enthusiastic if powerful light monsters came out because they know that nothing seeping out is no good.
All the beings in Pandemonium knew that experiencing a calm after such turbulent times is not a good omen. They already know that sealed inside that space is the Goddess of Light Luminaria. They would have liked it more if she struggled and expressed her wrath by creating more monsters.
