Elf Country

Elf Country (エルフの国) is a nation of elves in the New World south of the Slane Theocracy. The nation is also currently at war with the said neighboring country.

Background
The Elf Country once had a friendly relationship with the neighboring Slane Theocracy, despite the latters prejudice towards non-humans. That was until the Elf King abducted and raped the woman who was known as the ace of the Theocracy's Black Scripture. Unfortunately for the Elf King, the Theocracy managed to rescue her and took custody of the child he impregnated her with.

Afterwards, the Theocracy began waging a war of retribution against the Elf Country. However, progress is slow as the Elf Country is mostly hard-to-traverse woodland and the war continues to this day. On the other hand, the elves are clearly on the losing side, with many being captured and enslaved.

The Ruler of Conspiracy Arc
Following the founding of the Sorcerer Kingdom, the highest authority of the Slane Theocracy, the Supreme Council, wanted to directly engage them. However, they couldn't spend the manpower as their forces were already spread thin due to the war with the Elf Country. After the Supreme Council's meeting, they decided to continue to primarily focus on their war with the Elf Country.

The Craftsman of Dwarf Arc
The Slane Theocracy started to advance deeper into the Elf Country after it committed its Holocaust Scripture to the war. Desperate, the elves pleaded to their king to use his great power and save their nation. However, the king refused to aid his own country, seeing it as a nation of weaklings. He instead intends to directly visit the Slane Theocracy himself after the Elf Country is destroyed.

The Witch of the Falling Kingdom Arc
After conquering the Re-Estize Kingdom, Sorcerer King Ainz Ooal Gown despaired at the increased workload this would bring. He thus planned to put the Sorcerer Kingdom through a practice drill in case he were to go missing, which was really just an excuse for him to go on a vacation to the Elf Country with Aura and Mare.

The Half Wood Elf God-kin Arc
Unfortunately for the Elf Country, as a result of the Fall of the Re-Estize Kingdom, the Theocracy began utilizing its full military might in its war with them in hopes of ending the conflict swiftly. At this time, however, the Elf Country also just happened to be receiving a diplomatic visit by Sorcerer King Ainz.

Culture
All elves within the New World especially those who live in the Elf Country see any elf with Heterochromia eyes as a sign of royal blood. At least some elves have been known to mate with other humanoids and produce half breeds. Evileye noted that the Elf Royal Family was said to bear the special characteristics of the ancestral elves.

Religion
Rather than any conventional religion, the elves' blind following of anyone of their race with Heterochromia eyes implies that they worship them as gods instead.

Politics
The Elf Country appears to be an absolute monarchy, with the Elven King serving as its sole governing entity.

Military Strength
The Elf Country has a strong enough military to fight off the Slane Theocracy's, the strongest human nation in its part of the New World, for a long time. However, this is partly because the Theocracy never fully commited it's full forces to the war effort and there is still a distinct difference between the power of the Theocracy and the elf nation. This is proven when the Theocracy's progress greatly sped-up once it began to put more resources into the conflict.

The reason why elves are able to combat Theocracy's superior tactics, resources, troops, and magic items is their guerrilla tactics. To some extent, the Elf Country's military is said to be even more skilled than the Theocracy's Holocaust Scripture in this field.

Slane Theocracy
The two countries were once allied nations and had a mutual co-operative relationship but something went wrong and now they are at war with each other. Apparently, the Elf King kidnapped one of the Theocracy's Black Scripture members and raped her causing a deep animosity between the two nations. The Theocracy considers them lower than humans and as such any captives are most often treated poorly and even kept as slaves.

Until recently, the Theocracy and the Elf Country have been in a stalemate in the Great Forest of Evasha. However, upon the Theocracy deploying the Holocaust Scripture against them, the Elf Country is now being slowly overwhelmed and are expected to be soon conquered.

Baharuth Empire
While official relations have not been established, the country does own a large variety of elven slaves, so it is presumed that official relations between these two countries is not good.

Sorcerer Kingdom
The Elf Country has yet to make contact with the Sorcerer Kingdom. In fact, the Elf King doesn't even seem to be aware of the country's existence. Sorcerer King Ainz Ooal Gown, however, took an interest in the Elf Country and intended to visit it.

Eventually, after conquering the Re-Estize Kingdom, Ainz has decided to personally visit the Elf Country together with his Floor Guardians Aura Bella Fiora and Mare Bello Fiore in order to get them to make friends with their fellow elves.
