## Environment

As compared to Arthur's memory of the sunny world above the ground, the Demon Realm's environment was much worse. The light source came from the two "stars" in the sky. Although they are called "stars", their light and heat was far less than that of the sun for the earth. Most of the time, they were covered by the clouds of smoke in the air. In the evening, they became "the moon" again, emitting a faint icy brilliance. The temperature difference between day and night was very large.

There are two purple moons at night.

### Demographics

The Demon Realm had far more women than men, especially the succubus family which was purely consisted of "female". Strong male demons generally had many wives, and even powerful female demons had many "toy boys". Not only because of sexual desire, but also because of inheritance. Perhaps it was due to the relationship between bloodlines and eugenics. The stronger the demon, the lower the fertility rate.

For the Great Demon family, the stronger the mutated bloodline, the fewer the offspring. Athena's father, the Empire's First General George Wells had twelve wives, which was very rare among the imperial noble, but he only had one precious daughter, Athena. Athena had excellent qualifications; at the age of nineteen, she broke through the Higher Demon bottleneck. If her powers that were close to that of the Demon King were made known to the public, it would definitely cause a sensation.

Joseph's father, Lord Josh, had nearly a hundred wives and concubines and countless other women who had no identity. However, there were far fewer offspring than women. Of the few countable descendants, only his two sons Joseph and Kanita were noteworthy.

Of course, the mutation of bloodlines was not only based on heredity, otherwise there would be fewer and fewer powerhouses in the Demon Realm. Breaking the bottleneck by oneself was also a way to induce mutation. For example, if Arux broke through the limit of Higher Demon now, a mutation was likely to happen. Even if he himself did not mutate, there was a considerable chance that his future generations would have a mutated bloodline.

### Aging

The difference in strength also meant a huge difference in lifespan. This difference could not be narrowed by external factors such as longevity potion. The lifespan of ordinary demons was 200-500 years, and the lifespan of royal families was relatively longer. After the middle level (Demon King, Great Demon King), the lifespan would be extended by about half, and after entering the upper level (Demon Emperor, Demon Overlord), it would be doubled or more. Generally speaking, a Demon Overlord powerhouse's lifespan was at least 1,000- 2,000 years.

After stepping into the Kingdom level, the trainer could absorb the natural strength to replenish energy, and he did not have to completely rely on food to sustain life. His vitality was also greatly enhanced by the force of nature and law, and his lifespan would be extended by 10 times. After reaching Demi-God or Pseudo-God, this ratio would increase significantly.

The life span of demons was generally hundreds of years, so he couldn't judge from the appearance alone. Generally speaking, their lifespan increased as their strength increased, but their fertility rate would also decrease. Therefore, it wasn't surprising that Rummenigge was Fini's grandfather.

### Nobility

The titles of the Demon Realm empire in descending order were: Prince/Princess (royalty only), Dukes, Marquis, Earls, Viscounts, and Barons. Among the four lords, Shea was the lineage of the Lord of Midnight Sun and held the title of princess. The other 3 lords were just Marquis. Only a few elder families and the first general of the empire, George, held the title of Duke.

### Language

The Mozu speak some demon lingua franca different from human language, but one that Chen is able to understand somehow.

### Alchemy

Chen Rui remembers from his past self Arthur's incomplete memory:

"The alchemy of this magical world could be divided into two major categories: mechanics and pharmaceutics. In fact, it includes comprehensive knowledge of mathematics, smelting, medicine, magic array and so on. Due to its advanced level, few people could reach the master level and were highly looked up to in both the Human Realm and the Demon Realm."

The Demon Realm residents apparently don't know what pencils or paper are.

### Practices

According to the Demon Realm's practice, when certain contradictions couldn't be reconciled between the lords, they could be resolved by physical force. However, because it was an internal struggle in the empire, a special approval from the emperor was required.

Generally, the capital would send an envoy to work on the final mediation. In case the mediation failed, the role of envoy would become supervision to avoid excessive casualties. Generally speaking, even if one party won, they couldn't kill the lord of the losing party. The losing lord would be handed over to the capital for the final judgement. The loser could cede the land for compensation, or even be imprisoned.

## History

### Three Kingdoms

The Demon Realm originally had 7 royal families. After countless battles and eliminations, only 3 royal families were left in the end. They were the Lucifer royal family who reigned over the Fallen Angel Empire; the Mammon Royal Family (玛门) who reigned over the Bloody Empire (血煞帝国); and the Asmodeus royal family (阿斯莫德王族) who reigned over the Dark Shadow Empire (阴影帝国). These 3 empires in the Demon Realm had their own strengths and weaknesses. They had stood for tens of thousands of years.

### Beelzebub Rebellion

*See also: Beelzebub Incident, Glorfin*
Dark Moon Estate was originally one of the most prosperous estates of the Fallen Angel Empire. However, the Beelzebub Royal Family who had disappeared for many years suddenly revived in the Dark Moon City 400 years ago, led by a powerful demon named Glorfin Beelzebub. Glorfin was holding the artifact of the Beelzebub Family, the "God-Eating Mask". His power was tyrannical. He blatantly killed the Dark Moon Lord and several strong demons. He quickly controlled the entire Dark Moon Estate and began to invade the nearby Red Spirit Estate, subsequently subverting the entire Fallen Angel Empire.

Baiye Lucifer the Great led the army to attack Dark Moon. With Lucifer Family's artifact, "Sword of Fallen Angel", he went one-on-one with Glorfin at the arena. The heavily-injured Glorfin used the power of artifact to escape, then his whereabouts were known ever since. This rebellion was also settled.

### Baiye Lucifer and the War with humans

The border enchantment between the Human Realm and the Demon Realm would weaken every 500 years, starting wars between the two worlds. Fallen Angel Empire's Baiye Lucifer / Lord of Midnight Son (白夜大帝) was the strongest of Demon Realm. He was respected by all parties. He served as the commander of the Demon coalition during the war with mankind about 300 years ago. He personally killed the 3 strongest humans. He once gave the demon army hope of returning to the bright world above ground. However, the Lord of Midnight Sun was suddenly backstabbed and killed by a mysterious strong man, resulting in the army losing a leader. The demon army was defeated in the end and forced to retreat to the Demon Realm.

After the death of Lord of Midnight Sun, the Crown Prince, Grim Lucifer (格林·路西法) was too young to handle government affairs. Two foreign enemies, the Bloody Empire and the Dark Shadow Empire were also eyeing covetously. Fallen Angel Empire was having internal and external problems.

At that moment, Midnight Sun's younger brother, also Grim's uncle, Prince Obsidian (黑曜亲王) stepped forward and temporarily took over government affairs. He was called the Regent. Although the strength and military power of Prince Obsidian was far less than that of Lord of Midnight Sun, Obsidian's political means were brilliant. Using the reason that his brother's solemn sacrifice for the demons and the remaining prestige of the Lord of Midnight Sun in the Demon Realm, Obsidian signed a non-aggression agreement with the Bloody Empire and the Dark Shadow Empire.

However, after the Prince Obsidian resolved the external crisis, he did not return the power to his nephew, Grimm. Instead, he monopolized the power and eliminated the dissidents, indicating his objective of replacing the throne. However, Prince Obsidian did not receive the approval of the Lucifer family's artifact "Sword of Fallen Angel" (堕天使之剑). Also, with the high prestige of Lord of Midnight Sun in the military, there were 2 out of 3 generals that supported the Crown Prince, Grimm. So, Prince Obsidian could only continue his title of Regent but he confiscated his nephew's "Sword of Fallen Angel" and secluded him at the desolated Dark Moon estate, secretly sending people to monitor and control.

The Dark Moon Estate was dangerous; it had poor resources; there were also rampant thieves; and it even had horrifying creatures in the estate, the estate couldn't grow and develop at all. Grim was depressed and died in such adversity, leaving two daughters in his late years, which were Princess Shea and little princess Alice.

### Shea

Since young, Shea was indoctrinated by Grimm's with the thoughts of regaining the throne and resulted in the development of her cold and tough personality. She was calm and determined. Unlike her relatively weak father, she had the model of her grandfather, Lord of Midnight Sun. She took over the Dark Moon City at the age of 16 and immediately established a prestige with a series of methods, governing the Dark Moon City successfully.

Yet, even with Shea's impressive ability and ambitions, she couldn't fundamentally change the nasty situation of the Dark Moon Estate. After the death of Grimm, another imperial general turned to the Regent, Prince Obsidian. The only military forces left supporting the Dark Moon was the first general George Wales (乔治威尔斯), also Athena's father.

General George was now guarding the Warlock Fortress at the northern border with the Bloody Empire. Three years ago, Athena came to the Dark Moon City under her father's inspiration to show others that General George continued to support the Crown Prince's bloodline.

Over the years, Prince Obsidian had been non-stop studying the "Sword of Fallen Angel" that supposedly belonged to Shea. Once he could unravel the mystery of the artifact and got the approval of the artifact, he would be justified as the true emperor. Even the opposition led by General George could only acknowledge allegiance.

"It wasn't easy for Princess Shea; she almost single-handedly supported the Dark Moon Estate. His Royal Highness (Grim) was very strict on her. She has been carrying tremendous pressure, so she gradually developed a cold personality. Even Alice was afraid of her. Yet, according to Alice, Princess Royal was actually very gentle when she was young..."

### Alvin

After the war, the Dark Moon Estate no longer prospered like the old days. Following the death of the Lord Baiye, the Regent Heiyao expelled his nephew, Grim who was supposed to inherit the throne to be the lord at Dark Moon. He then used multiple ways to monitor and control, making the Dark Moon to further decline. Although after Princess Royal, Shea inherited the throne, she rectified and reformed greatly, she still couldn't get rid of the poverty from its root.

Joseph Alvin, the finance officer of Dark Moon City, was the eldest son of the Red Spirit Lord, Josh. On the surface, the Alvin Family was funding the Dark Moon Estate, but it was actually controlling the economy of Dark Moon. Today, Joseph controlled the only Chamber of Commerce and half of the shops in Dark Moon City. Even Dark Moon's food supply was mostly from the support of the Alvin Family. Obviously, it was a treacherous means by Heiyao to control the Dark Moon Estate via the Alvin Family.

In terms of military, although the first general George Wales's daughter, Athena was in the Dark Moon, the army of the estate was in the hands of Callon Family's Alan. Initially, the Karon Family supported the Crown Prince, Grimm, but they later submit to Regent Obsidian. The military power that truly belonged to Shea was the Imperial Guards headed by Kaguron.

It was the mess left by the Crown Prince, Grimm but it was also forced by the situation. The 2 most important things: the economy and military were in the hands of others. Shea still couldn't do anything until now.

Athena wasn't elaborate with most of the things. Chen Rui didn't understand until now that Shea's situation was worse than he thought. He suddenly understood the reason why Princess Royal was cold and strong. Perhaps this was the only way to support the burden left by his father.

There are many burdens in life. Some aren't the burden that we have to carry.

If the Lord of Midnight Sun was still alive; if Grimm could inherit the throne, the once gentle sister in the little princess's eyes wouldn't need to wear the cold mask. It's just that the mask might have become a part of her now, and it's likely that it couldn't be removed anymore.

### Current situation of Fallen Angel

"Athena's father, General George, is the biggest supporter of Shea. He is currently guarding the Warlock Fortress at the northern border of Fallen Angel. I heard from Athena that although the three countries signed a peace agreement, the Bloody Empire often harassed at the border. Sometimes they even launched small scale battles, yet Emperor Raizen of the Bloody Empire turned a blind eye to this, and he didn't restrain his army."

Shea said, "Back then, Prince Obsidian used the Lord of Midnight Sun's sacrifice for the Demon Realm as a reason to sign a peace agreement with the Bloody Empire and Shadow Empire. However, Obsidian can't rival with the other two emperors regardless of its strength, prestige or talent. Thus, the two empires have been eyeing the Fallen Angel Empire covetously, especially Raizen the Great. Besides, Shadow Empire's Catherine the Great isn't simple too. Not only her strength isn't much inferior against Raizen, but she is also the first wise sage of the Demon Realm. The Fallen Angel Empire has fallen from the strongest empire to the weakest."
