Jack and Jeanny received the good news from John that the Liguritudum army had retreated. The invasion had been repelled, but they didn't have the time to rejoice. They were not out of the woods yet, they still had to survive the demon horde brought out by their disaster item.
The two with the support from Jack's clones, Therras, Grace, and Paytowin had been battling the demon lord boss while everyone else kept the other demons at bay. Jeanny was fighting the demon lord in the air using a wings tool. It was another thing she had acquired from the Council of Elpo.
The demons had managed to push deeper into the palace courtyard. The defenders tried to maintain their formation, but none of them was a tactician at John's level. As the battle progressed, the situation became very chaotic and it was pretty much a free-for-all state.
