Vyashion

The Vyashion continent (バイアシオン大陸, Baishion-dairikyu) is the fictional main setting for the Zill O'll continuity. Its inhabitants and architecture resembles medieval Europe with a few Asian inspired influences.

While it is possible for the player to completely ignore its history during their playthrough, the legends of the land help elaborate on many events which occur during Zill O'll's story.

Creation
At the dawn of time, there was two primordial forces: light and darkness. When they converged, they formed an infinite void which spiraled into eternity. Within that void was the silent wishes of beings not given life. These wishes eventually gave birth to a single will. This will manifested into the most holiest of deities which, after several cycles of its whirling existence, decided to create a world. Shifting itself briefly to create a spherical mass, the world was created between the two realms of light and darkness and was gifted by the holy deity with life.

The first deity to emerge was Nortun, the Sky God, later known as the "All Father" and leader of all gods. Choosing to have a neutral yet vigilant rule over the world, he formed the land's skies to forever watch over it. He was wed to the second eldest deity, Asrada, the Sun Goddess, to grant the world light. From their union, supernatural beings were granted sentience for the first time. Many gods were birthed from their union. Tiera and Vyas, twin sister and brother respectively, were the eldest of their children.

Tiera, the Mother of Creation, wanted to gift the world with life. She created nature and mothered the deities for elemental powers for the world (Fire, Water, Earth and Wind). A land of many beasts, spirits, and natural wonders, it was a miraculous and harmonious paradise ruled by her four children. She adored all of her creations as though they were her own children.

However, the holy deity was not pleased by her selfish desire. It felt that the world was amiss and sought to add variety. Borrowing from elements of the world and the void around itself, it morphed and shaped these masses together with purposeful imperfections. The fusion created humans. Humanity accepted Nortun as their divine creator, thinking that the clouds and morning sky were the god's method of communicating with them.

Tiera's Revolt
Humanity plundered the land, slaughtered beasts to sustain themselves, and killed spiritual entities to steal their powers. Feeling as though her "children" were being robbed, Tiera harbored a strong resentment towards humanity. Nortun, who agreed with their creator's wishes, tried to pacify her, but his words fell on deaf ears. She had already been swayed by the gods of the underworld to give into her hatred. Corrupted by her malevolence, the goddess conjured thousands of demonic beasts to annihilate humanity and rebel against the other gods. These beasts were later dubbed to be Tiera's Daughters –regardless of the beast's true gender.

To counter his elder sister's aggressions, Vyas, the God of Earth, assembled an army of his own. With his father's permission, he created twelve holy giants; each were endowed with powerful abilities to slay Tiera's Daughters. From the land's elemental powers, he created three divine dragons (Dragon King, Ocean King, and Flying King) to counteract Tiera's elemental children. Vyas granted command of the main army to his younger brother, Ulugh.

After much bloodshed, Ulugh struck the decisive blow against Tiera. Even when fallen and wounded, she still posed a viable threat. Therefore, her body was dissected into four pieces and sealed within four quadrants of the land. Upon learning their mother's fate, the four elemental spirit gods surrendered to Vyas. The five surviving giants were ordered to guard the seals over Tiera's body.

Nortun rewarded Vyas by naming the land in his honor: Vyashion. Ulugh was anointed with the title God of Heroes. Wanting to live the life of a human, however, he respectfully stepped down from godhood. Nortun respected Ulugh's wishes by granting him a mortal body.

End of Gods
Peace had returned to the land, but the holy deity was not pleased. Its creations gave birth to joy, anger, and sorrow and celebrated a pointless massacre. These emotions seeped into its private realm and it was disturbed. It requested for Fanatic, the Goddess of Capriciousness, to intervene with the threads of fate. She chose to target humanity's hero, Ulugh.

Ulugh's heart was captured by a kind and gentle woman named Sistina. She felt sympathetic with Tiera's feelings towards her children and sought to nurture and respect whatever wildlife, plants, and spirits she had encountered. Her actions were rejected by her fellow men, especially by victims of the war. When Ulugh was away, she was killed by an angry mob of people. The former God of Heroes learned of Sistina's wrongful death and pleaded for retribution to his chief. Nortun sought to uphold the gods' neutrality with mortal affairs and would not entertain his further inquiries. Other gods who supported their chief's decision did the same.

Isolated and ignored, Ulugh was at a loss. A bodiless Tiera sensed his inward fury towards Nortun and tempted him with a pact. If Ulugh swore to obliterate humanity, she would revive Sistina for him. He agreed and his soul was corrupted, transforming Ulugh into a demon. Both parties honored their side of the contract. Yet Sistina's soul rejected her second chance at life and scattered. Her hopes glittered as the light within Vyashion's living beings, or Souls. Her love for Ulugh manifested as stars in the night sky so as to watch over him from the heavens. Sistina's empty immortal body remained within the underworld as its new reigning goddess.

Too vile to realize Sistina's condition, Ulugh proclaimed war on gods and humans. His elite knights, the Twelve Knights of Round, were also converted into demons in loyalty to their lord. Dubbed the Knights of Darkness, they were a formidable force in Ulugh's army and laid waste to thousands with their enchanted artifacts, or Weapons of Darkness. Later generations would learn that anyone could use these artifacts at the cost of corrupting their soul.

During the war, Ulugh killed Vyas and drank his brother's blood to boost his own strength. Granted with the power to create, he molded and gave birth to four evil dragons. Ulugh's demonic sword, Sol Revenge, was also a force to be reckoned with as its blade was permanently stained crimson with the blood it had shed. He would be known as the God of Destruction, and Vyas's death by his hand had plunged Vyashion into a dark age.

Concerned with protecting what remained of humanity, Nortun summoned forth a god from the parallel dimension to fight Ulugh's forces. The god who came to him was Solias, the God of War, who could wield seven weapon simultaneously. Amazingly, he and his two nameless companions were all it took to completely change the tide. The trio defeated the Knights of Darkness one by one, and victory shined in humanity's favor. The war between gods intensified, however, and many deities were slain in the conflict.

Solias cared little for Vyashion and its inhabitants, only adhering to Nortun's request to spare humanity. It became personal for him when Ulugh killed one of his companions. Invigorated to end the war for his departed friend, the God of War charged towards the God of Destruction. The battle between them was fierce and punishing. Each strike from their swords resonated throughout the world and shook the landscape. Missed blows shaped Vyashion's mountains and tore the seas asunder. After a long and tiring fight, Solias prevailed when he allowed himself to be struck by Ulugh. He then used this opening to vanquish Ulugh's body. Their duel would later be a popular legend for artists and authors to retell.

Ulugh's soul was sealed at Dark Gate Island. Any remaining evil spirits and beasts were sealed in the hopes that they would never rise again. The God of Destruction's war caused the surviving gods' to become aware of their meddling with mortal affairs. Gods who were loyal to Nortun chose to depart from Vyashion and forever stay within their parallel dimension. Others who had perished during the war either joined them or chose to sleep within Vyashion without a bodily host.

Aftermath
Vyashion was deprived of gods, and their history was all but forgotten by humanity. Yet their servants remained. The giants kept watch over Tiera's body even during Zill O'll's main setting. The three divine dragons were not sealed and were free to live as they saw fit.

Dragon King, the eldest of the trinity, decided to inherit Nortun's will. He believed mortals should be ruled by deities to maintain the balance of the mortal world. With his two brethren, Dragon King taught mortals the world's history but omitted the details regarding the gods' birth and departure. Instead, he focused on the war with Ulugh and heroics of the deities involved. To keep the charade, he and his brethren posed themselves as gods. Mortals then worshiped the gods and dragons equally. Unbeknown to the dragons, the true history of the world was chronicled by the first elf and kept within the elves' paradise.

Although the Dragon King claims to be mutual like Nortun, he still intervenes in human affairs.
