Julius took Selphira underground alongside the wall army.
For the moment, attacks had stopped. Without Sirius at the front or Selphira pressuring the rear guard, Kharzan's army wouldn't have many reasons not to attack them full force in the worst case scenario.
So striking now that they had halted their march and enraging them was unnecessary.
Only some aerial fights for information dominance continued happening consistently, scouts from both sides trying to maintain surveillance over enemy movements mostly without engaging in serious combat.
Julius was taking advantage of this respite to absorb more soldiers from the abyss wall. His numbers had grown to 5000 soldiers, and Arturo's report indicated that 2000 extra soldiers were already gathering at the castle as strategic reserve and continuing to increase.
But Kharzan's army wouldn't take long to reunite, surrounding Selphira's wall and recovering the strong structure of their frontal formation.
Time for maneuvers was limited.
