However, on the one hand, they have to deal with the invasion of barbarians from the north. On the other hand, there seems to be discord in the mountain fortresses on the island. In order not to repeat the mistakes of their predecessors, the two old friends once again embarked on the arduous journey to hunt down the Mother of Demons. Only this time, there is a more mysterious, powerful and bloodthirsty third party force secretly observing and waiting...
