Aberion Hills (アベリオン丘陵) is an area patch of wilderness with vast hills that lies right between the borders of the Slane Theocracy and the Roble Holy Kingdom.


In the past, this area was home to a kingdom of hill dwarfs, but it was destroyed by demi-humans. Currently, it is a lawless area where a myriad of demi-human tribes fight day and night for control. The constant warfare and dangers these demi-human races produce is so troubling that the Roble Holy Kingdom constructed the largest and longest wall barrier on the continent to keep them out. The Slane Theocracy have made ​​numerous attempts to subjugate and cleanse the area, but so far its efforts have only managed to temporarily thin the demi-human population.

In the past, the Adventurer's Guild of the Kingdom had sent people there, but none have ever returned in one piece. As a result the area is completely unknown terrain to the kingdom's citizen.
