Abelion Hills

**Abelion Hills** (アベリオン丘陵) is an area of wilderness with vast hills that lies between the Slane Theocracy and the Roble Holy Kingdom. It is inhabited by all kinds of demi-humans who are constantly trying to invade the Holy Kingdom. Jaldabaoth conquered the region and ruled over it until the Sorcerer Kingdom laid claim to the territory.

## Background

There were all kinds of demi-humans in the hill region, yet they did not have good relationships with each other. Rather, they often fought over territory, and apart from cases where Ogres took Goblins as slaves and cruelly used them, these races very rarely worked with each other.

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 Re-Estize 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 citizens.

One of the most influential demi-humans to come from this land is Buser, also known as the King of the Demi-humans. Buser was a Bafolk famed for his strength as he managed to unite all of the Bafolk tribes under him as well as conquering many other demi-human tribes in the region.

### The Ruler of Conspiracy Arc

*Main article: The Ruler of Conspiracy Arc*
As part of Ainz's persuasion to get Pluton Ainzach to trust him in turning the Adventurer's Guild from a mercenary group to real adventurers to explore the unknown and new lands. Ainz used the Aberion Hills as an example of what sort of potential exploring new lands would mean to the adventurers.

Ainz also spoke of providing support and assistance to all guild members if they would agree with his new reforms and is also seeking to use their help with finding more detailed information of the people that live there and what opportunities the land itself could provide.

Furthermore, Ainz mentioned that the Sorcerer Kingdom is making preparations for any potential future conquest, however only once that available information is procured and assured that he will not involve the Guild in their subjugation.

*Main article: The Paladin of the Holy Kingdom I* *and* *The Paladin of the Holy Kingdom II Arc*
At some unknown point in time, Demiurge, under his Jaldabaoth guise, conquered and enslaved about eighteen different demi-human races from the Abelion Hills in his conquest of the Holy Kingdom. He then forced all those who were combat-ready into a huge allied army and attacked one of the fortresses at the Holy Kingdom's Great Wall. After Jaldabaoth single-handedly destroyed the fortress along with a section of the wall, he ordered his army to finish off any surviving soldiers. Once that was done, the demi-human army marched through the opening in the wall into the Holy Kingdom.

After Jaldabaoth invaded the Holy Kingdom and conquered the North, he left one of his trusted demon subordinates and servitude of demi-humans under them to manage the territory while its other brethren attacked cities like Loyts.

When Ainz Ooal Gown supposedly was killed by Jaldabaoth, it was believed that he has fallen into the Abelion Hills. Fortunately, he miraculously survived the first deathmatch with Jaldabaoth, reappearing with his own demi-human army. He fought in his second and final standoff with the said Demon Emperor as the latter was about to destroy the Holy Kingdom Liberation Army. He said that he merely fell into the Abelion Hills region, where he has recuperated, and rallied the local demi-humans before coming back to overthrew the reigning demon. Whereafter he claimed the region for the Sorcerer Kingdom.
