The battle at the two fronts raged on. Both sides suffered losses. The losses on the underworld forces were greater since the defenders had advantages on the defensive structures and siege weapons. However, these defensive structures and siege weapons were decreasing as time passed. On the other hand, the underworld forces seemed unending.
After two days since Beelzebub arrived, Ragorth at the North defensive line called for a retreat. If he persisted in fighting, they would lose too many troops. Without troops, the remaining defensive lines would be useless.
The Council of Virtus originally expressed a strong objection to this decision. They refused to retreat and wished to continue fighting. Luckily, Megan talked them out of it.
Mihos and Pallas had learned to respect outworlders after their experience with Jack and Paytowin. Hence, they didn't dismiss Megan's words. This allowed her to make them see reason. A planned retreat was not a defeat. It did not taint their courage.
