Origin of The Underworld and The Mortal Realm
by Onyxe Blade
Everyone knows the story of how Lucifer challenged the Heavenly King and fell from grace and thus became Satan. Alongside Lucifer were his fellow angels who grew tired of their creator. Knowing their creator's plan of creating new lifeforms known as humans, Lucifer and his like-minded brethren challenged the Heavenly King, only to be cast out of Heaven as they fell into the world below the land of mortals. This place would be known as the Underworld, the home of the former fallen angels transformed into monstrous beings known as demons. Angered that their former ruler discarded them like yesterday's newspaper, led by Satan, the demons plotted against the Heavenly King and the impending birth of his new creation known as mortals. Satan and his cohorts devised a scheme to ruin the Heavenly King's creation. The Heavenly King created the first group of humans: two heterosexual men, two heterosexual women, two male homosexuals, and two female homosexuals. The heterosexuals jobs were to maintain the garden and procreate while the homosexuals tended to the animals of land, air, and sea. The mortals lived happily in the Garden of Salvation unaware of Satan's schemes against them. Luckily, a goddess by the name of Persephone, who unlike the Heavenly King, did not abandon Mystilia to create their own realm and species of people, but took interest in her fellow God's creation. Sensing that something sinister was going to befall them, but didn't know when or the source of the incoming evil, Persephone performed a spell on them she called "Saver of Innocence". She used it on the mortals, knowing that it would prove beneficial in the near future.
Satan made his move and corrupted the mortals into performing sinful acts such as adultery, lying, and murder. Satan even intended for one of the male homosexuals to rape one of the heterosexual men. Fortunately, thanks to the spell Persephone placed upon the mortals awhile ago, despite being plagued by several sins, the sin of rape would never exist in a pure mortal. Witnessing the corruption of his creations, the Heavenly King ordered his angels to cast them out of the Garden of Salvation. He was furious that they allowed themselves to be corrupted by the devil by eating from the Sacred Tree, which he commanded them to never eat from, no matter the reason. These events led to the beginning of mortals living life according to how they saw fit; no longer living to please a God that never gave them a say in being created in the first place. A few centuries later, other gods and goddesses from the realm of Mystilia would also create their own sentient beings on the mortal realm such as beasterians, fairies, elves, orcs, goblins, and other mystical creatures. Persephone then granted the beings of the Mortal Realm magic alongside her fellow goddess Hecate. This brought rise to the age of magic, which further pushed the Heavenly King away from attempting any re-bonding with his creations. Now having access to magic, the beings of the Mortal Realm no longer cared to acknowledge their creator, and lived life on their own terms.
Of course, life in the Underworld was nothing short of chaotic as demons turned on one another when an enormous power struggle erupted in the Underworld. Each demon had his or her own reason for wanting to be the supreme ruler of their realm. Ultimately, it was Satan alongside his other high ranking demons: Leviathan, Lilith, Beelzebub, Belphegor, Mammon, and Satavorus. Of course, there were many powerful demons in the hellish realm and it took great effort from Lucifer and the other Demon Warlords to do their best to maintain some sought of order. However, over time, the Demon Warlords plotted and schemed against one another and many wars broke out in the demon realm; along with the ongoing battle against the beings in the mortal realm and the eventual arrival of the goddess Persephone to the Underworld. The goddess became something of an unwanted rival to Satan as she made it her duty to keep the demon tyrant in check from going too far and she controlled the amount of demons that could go hunting for mortal flesh.
With the aid of her fellow goddess, Hecate, Persephone granted a magical increase for the mortals, giving them even greater knowledge of magic to use against their opposition. Such actions even resulted in some mortals being born with magic, who are referred to as Naturals. Unfortunately, due to being plagued by sin, the mortals were not only threatened by demons, but became a danger too themselves. Many of them developed their own ambitions and that caused many conflicts. This eventually led to the first of many wars in the Underworld.
Satavorus wanted absolute control of the Underworld and knew he needed to kill both Satan and Persephone to achieve his goal. Many demons sided with Satan and Persephone while others sided with Satavorus. During the climax of the war, Satavorus killed Persephone, who became Satan's lover over the course of their many centuries together. While Satan was devastated to lose the woman he loved, he managed to avenge her by finally driving off Satavorus before resigning himself to a part of the Underworld no demon could reach, and acting as the god of that realm. Meanwhile, Satan's descendants became responsible for maintaining order in the realm alongside demons who either remained loyal to Satan, such as Leviathan, or demons that managed to rise to power by any means necessary, such as Koga Yukimaru and Othello Strongs. The current ruler of the Underworld and its capital, Satan's Landing, was the demon Johanna Lucifera. While Persephone tragically lost her life to Satavorus during the war, the goddess was not without her own backup plan. Before her death, she performed a spell that would allow her to reincarnate into a powerful soul regardless to whether it was mortal or demon.
Many centuries later, mortals made great advances in magic, technology, and other areas to improve their way of life. A country by the name of Mayland only had a handful of States, but grew over time until it became 75 known States. While many countries had their own way of operating, Mayland was the first and only country to operate on a unique rulership system in which one must prove oneself the strongest among others in order to rule the land as they saw fit. Mayland's first ruler was a mortal woman named Anuli, simply referred to in legend as The First. Anuli served as Mayland's ruler and protector for years as she hosted a tournament called The Devilry Combat to find a suitable replacement to her throne. Unfortunately, no one managed to best Anuli in battle and the Queen eventually passed away due to old age. Since Anuli never had any lovers or descendants, other mortals and sages battled among one another and the strongest became Mayland's next ruler. No matter the method of one becoming Mayland's future King or Queen, all rulers were to continue the tradition of The Devilry Combat Tournament. Many centuries and many rulers later, Mayland would be ruled by King Onyx Carnival, the 135th ruler and the country's first half-demon to rule over it; succeeding the previous ruler, Queen Ida. Demons were viewed as the natural enemy of mortals; however, over the past numerous centuries, demons and humans managed to form more positive relations despite not all humans and demons sharing the same values. They still viewed one another as predator and prey. Thankfully, the positive outweighed the negative; along with King Onyx proving himself as one of Mayland's most suitable rulers. Hopefully, such actions will bring demons and mortals closer together in time.
