The demons had already sent out the message to the Southern continent, telling them about the plan to launch an attack on Aragon Island and reclaim it. The Southern continent sent a message back agreeing to the plan and informing the demon lord exactly how many troops they had left in the army over there as well as the number of ships and how quickly they could move to provide support from the southern part of the island.
With this information, Mark, Hunn, and the rest of the council members were able to refine the plan and reorganize the soldiers. The Southern continent would attack Aragon Island first and they would be responsible for causing as much havoc as possible to distract the angels so that the main group from the northern island could join in.
