There is an unclaimed land that separates the Losea Kingdom and the Chodora Kingdom.
Needless to say, the land is filled with different kinds of beasts as no one regularly hunts them. Aside from that, it is also a perfect place for criminals who need to escape from being hunted.
The thick forest and natural landscape can be a huge problem to their pursuers…
Of course, the two kingdoms wanted to take the land for themselves in the past decades and it resulted in many skirmishes and assassinations to the important individuals of each kingdom, but it didn't blow up to an all-out war since there is one organization that would benefit from it.
It is the Three-Eyed Imp Cult that needs tons of blood to summon their evil god…
As a matter of fact, there are already a couple of cases where they successfully summoned the Imp and resulted in a massacre of the kingdom's soldiers.
