"We can't enter the main hall," Negris said.
Right after he spoke, Ange took a step into the main hall. Supposedly, there should have been a barrier there, but Ange now stepped right through it as if it were nonexistent.
Negris quickly flew over, successfully passing through the spot where the barrier supposedly was.
"Has it really disappeared? We can go in," Negris rejoiced, and everybody rushed to follow.
The Resting Palace, with its main hall and four other sub halls, was built using a multi-layer stacking method of dimensional space. Each building was a separate dimension, therefore corresponding conditions must be met to enter the dimension within the palace.
According to Durken, achieving balance was necessary, but how to attain that balance, he did not know. The current Resting Palace has completely changed from the time he designed and constructed it.
