According to Aeon's original crazy plan, they would continue to kill the Orc Groups that come to the Goblinthorn Village again and again roundwise.
With each round, the number of Orc Groups coming to the Goblinthorn Village will increase and along with them, the difficulty for Aeon and the Goblin Followers will increase too.
Nevertheless, Aeon believed that the rewards from the Grimoire of Life and Death from offering the Monster Corprses would somewhat decrease the difficulty of the next round.
However, the number of Hornless Orcs in the second round was more than what Aeon expected and he believed the Orc Captain would send an even greater number of Orc Groups to the Goblinthorn Village in the next round.
Thus, Aeon changed his plan from being defensive to being offensive.
That's right!
Aeon decided to attack the Bloodaxe Village and that's the reason why he asked Warthorn to gather the Goblin Soldiers as soon as possible.
