The world was once victim to a previous scourge of Demons in an ancient past before King Allant came to the throne. The Old One, an entity of unfathomable power, had awakened thebane of existence into the world, unleashing terrible Demons that ripped the land asunder, consequently exterminating half of humankind. Those that would become the Monumentals sought to spare the land from further harm, and combined with their knowledge of Soul Arts, returned the Old One back to its slumber. To divide the lands amidst different regions and to return life to where there was none, they ordered Archstones be constructed and placed throughout the world, all of which were connected to a central Archstone used for inter-regional travel.
Amidst the realm of reality and death exists a place known as the Nexus, a hub for the souls whom traverse the ethereal worlds hoping to reclaim their bodies. Below the Nexus sleeps the Old One, offering the promise of limitless prosperity to any that gives him or herself up to it. King Allant the XII of Boletaria dreamed of bringing eternal wealth to his mighty kingdom, and thus gave himself wholly to the Old One’s will, awakening it from its long slumber. Prosperity did not befall Boletaria, but instead the colorless fog of chaos and calamity blanketed the lands, and those still living were soon no longer among the sane.
The many former-citizens of Boletaria once prayed to God to grant them divinity in life. Among the most notable figureheads of the Kingdom’s parish were Saint Urbain, a highly respected man of great spiritual knowledge and an abundance of faith, and the Sixth Saint Astraea, a divine Maiden worshipped for her purity. Urbain’s followers revered him as being in direct communion with God, and through him they believed His message was delivered. It is Urbain’s belief that the Demons were placed into Boletaria, and the fog consumed the Kingdom, as a test from God, and that all must use His miracles to banish the soul-thirsty horde.
The Boletarian Palace became home to the might of two fire-breathing dragons, and the three heroes of Boletaria transformed by the demonic fog. The Kingdom was once privileged to house the its finest heroes: Alfred, the Knight of the Tower; Metas, the Knight of the Lance, and Long Bow Oolan, who commanded a legion of archers. Their physical bodies were twisted and distorted into demonic entities while their souls remained to guard the pathway leading to their False King - a demonic embodiment of the true King Allant.
Stonefang Tunnel was an excavation site under the control of King Allant. The miners who devoted their lives to the soldiers of Boletaria remained stubborn in their fruitless efforts to support the king, and rather than attempt to flee when the fog approached, they remained behind.Now devoid of sentience and soul, they mindlessly continue to chisel away at the tunnels. The caves create a maze-like system beneath the excavation ground worthy of its name “The Tunnel City.” Rumors of the tunnels sitting on the shrine of an ancient dragon are abound; the ancestors of the excavators were said to have worshipped and revered the dragon as a god. At its core sits a temple devoted to a fire demon whose flames are said to be the very essence from which blacksmithing was begun.
The Tower of Latria was a shrine devoted to the Ivory Queen in the lands neighboring Boletaria. With her husband, Latria ruled her kingdom - encompassing a penitentiary, a church, and the great tower itself - to the great adoration and respect of her people. Latria banished her husband from the lands for unknown reasons, and when the fog bathed the kingdom, Latria’s husband found himself filled with a terrible and vengeful lust. He soon discovered the source of his mad desires - a beautiful and flowing golden garb that seemed to beckon his name. When he put the robe on, a rage filled within him. The old man returned and ordered his wife exiled from her own kingdom and her family imprisoned in the cells Latria formerly governed. In each cell block, the old man commanded inhuman guards to keep watch over the tortured prisoners for eternity. He oversaw the construction of an idol made in his wife’s image to give false hope to the inmates, and with the masses of flesh accumulated throughout the years, the old man has begun creating his own army of demons, among them the ravenous Man Eaters. Suspended from the middle of the tower is a large, mechanical heart, constructed in an effort to help maintain the old man’s own existence. The souls of the damned inside of the prison are used as life-giving sustenance to keep the heart beating. In time, the old man’s body began to whither and decay, and the golden garb - the true source of the old man’s demonic rage - beckoned a new host. Withthe old man rid of the robe’s life-force, he breathed his last gasp of air.
The Shrine of Storms was an isolated land where pagans would go to worship the god of Storms, and where legends of fallen heroes were mourned. The colorless fog released a flood of souls from the many catacombs, which soon found hosts in the skeletal remains littered acrossthe island. Tales of great pagan deities and Boletarian folklore gave birth to reality as the Shrine isnow home to fiction-made-flesh. Adjudicator, the great Judge of the Deceased, awaits the passingof a new hero to begin the process of purification before the soul is given up as a sacrifice to the great Storm King, a mighty beast that soars high above the island’s ancestral burial ground. The Storm King himself is merely the embodiment of the ideas of an ancient pagan civilization, given corporeal form by the colorless fog. Deep inside the ruins of the Shrine of Storms is a burial ground devoted to the legend of a great and nameless Hero who now blindly continues his lust forpower and fame, he as well a legend of a distant generation perpetuated by the pagan rituals.
The Valley of Defilement is a wretched home for the abused and neglected citizens of Boletaria. A dumping ground for the Kingdom’s unholy, the Valley became notorious as a place where one could leave the fetus of an unwanted child to rot in the festering swamps. Hearing of the Valley’s dreadful circumstance, the Sixth Saint Astraea took it upon herself and, along with hercompanion, Garl Vinland, traveled there in hopes of freeing the depraved souls consumed by the fog. The mindless drones that now remain in the Valley will violently attack any who threaten themin hopes of claiming souls to offer up to the great Maiden who showed them compassion. In the deepest pits of the Valley are born two vile demons out of the putrilage and plague that lingers in the deadly bog. It is said that Astraea pledged herself to the will of a Demon’s Soul to help ease the pain of the suffering, rather than to accept the aid of a cruel God who would allow such a place to exist
The Northern Lands were once home to the race of mighty giants. They lived in relative peace with the rest of Boletaria, until the thick, colorless fog swept in and blanketed their domain. The Northern Lands were the first to succumb to the spread of Demons, and in an effort to contain the madness, Boletaria sent hundreds of thousands of its finest knights to the great kingdom to fend off the threat. The effort was for naught, and the Archstone connecting to this land was later destroyed as a last-ditch attempt to contain the chaos. It did not succeed.
-is said to have once been one of the most powerful Demons in existence. Her certain ability to harness and manipulate the souls of the player-character certainly seems interesting. She maintains a direct communion with the Old One, and is even able to lull it back tosleep should the character accept her offer, making her considerably more powerful than it.
-is the last surviving harbinger of its kind. They are a vessel-race endowed only with prophetic knowledge and lacking all consequence of emotion or personal-thought. It seeks toaid the adventurer into lulling the Old One back to sleep.
-is a pilgrim of God and a devout believer in Miracles. He puts his faith in his Lord that prayer and worship will rid Boletaria of the Demons. He has many followers, few of which accompany him in the Nexus.
(There is great evidence to support the theory that the God in which Saint Urbain and his followers believe does not actually exist, but instead is a divinely-twisted version of the Old One itself. The “Talisman of God” states that it was crafted in the image of God, whereas the “Talisman of Beasts” was crafted in the image of the Old One. Moreover, the info page for the “Talisman of Beasts” clearly states that “The symbol of God was nothing more than the image of the Old One”).
-is a powerful spell-user who has devoted his entire research to further understanding the Soul Arts, a dark magic born out of the Old One’s demonic presence. He is at odds with Saint Urbain and believes the devout priest is worshipping a false God. Sometimes his lust for souls is greater than his desire to learn more about the Soul Arts.
-is the eldest member of the King’s elite duo known as the Twin Fangs. When the second-half, Vallarfax, fled the Kingdom and escaped the fog to warn the rest of the world of Boletaria’s plight, Biorr stayed behind to defend the honor of the True King Allant. He soon found himself at a great disadvantage against the Kingdom’s new demonic inhabitants. He possesses great wisdom and knowledge about Boletaria and an undying devotion to the real King, which he valiantly shows while aiding the player in battle.
-is a practioner of a darker form of Soul Arts the likes of which are often looked upon with great disdain by Urbain and the community. She was imprisoned by King Allant’s personal executioner, Miralda, and left under the watchful eye of one of the king’s deformed jesters.
-is a deadly assassin whose only business in Boletaria is to aid in the misdeeds of his accomplice, the enigmatic Mephistopheles, and kill all those who have learned the ways of Soul Arts.
-is grim woman with a deadly secret. She seeks the assistance of Yurt, and later the player if Yurt is killed, and wishes the death of key NPCs in the Nexus; specifically, those with knowledge of the Soul Arts. Upon completion of her requests, Mephistopheles will say that the Order of the Soul has commanded her to remove all those who know the ways of Soul Arts from Boletaria, the player included, in order to keep the ancient rite a secret.
-is the Prince of Boletaria, whose real name is Ariona Allant. He is one of theearliest encountered NPCs in the game, and most frequently-encountered through the entirety of World 1. Ostrava seeks council with his father, the King, but quickly learns of the demonic farce that now sits on the throne. Overcome with grief and betrayal, Ostrava kills himself at the foot of his father’s palace, offering his belongings up to you. Through various conversations the playercan have with Ostrava in the game, he reveals that the mighty Twin Fang Vallarfax ventured back through the fissure into Boletaria after warning the world.
(This might be considered an inconsistency, or an error on the part of the developers: Ostrava actually says that Biorr was the one who escaped through the fissure and that Vallarfax was never seen again, when in fact you see first-hand that it is the other way around. Depending on how you interpret this can change your opinion on the state of Vallarfax’s existence)
-is a demigod of the ancient past and the founder of Boletaria, locked away by the False King inside a great shrine which houses one of theKingdom’s most holiest of treasures - the Demonbrandt. The player receives the key to unlock and free Old King Doran from Ostrava’s corpse, and thus can challenge Doran to a duel for the right to claim the Demonbrandt
-is King Allant’s personal henchwoman and a stain on the Boletarian Kingdom. She is notorious for her brutality and lack of compassion, and has an unyielding devotion to the king even in his current demonic misrepresentation. She successfully managed toimprison both Yuria and Biorr, leaving the nature of her devotion and power in question.
(It was once believed that Vallarfax of the Twin Fangs had ventured back through the fissure and returned to Boletaria to aid Biorr, but that he was captured and killed by Executioner Miralda. Speculation arose when players discovered a set of Brushwood armor in the dungeon where oneencounters Miralda. Many had assumed that, since he was a member of a duo known as the “Twin Fangs,” both members would share matching armor sets. While still likely true, this has recently been put under skepticism when, upon further examination, it’s revealed that the armor set is not, in fact, exclusive to the elite group, but was once formerly the traditional armor of the Boletarian royal family. However, the Ring of Great Strength is exclusive to the duo, leading players to now assume that Vallarfax - still having returned to Boletaria - did not die by the hands of Miralda, but was killed by the dragon at their nest, where players can find several charred corpses, and most importantly, a Ring of Great Strength).
-is a plunderer who entered Boletaria through the fog in hopes of pillaging the riches of the deceased, but found himself trapped in a deep mineshaft of the Stonefang Tunnels.
-is among the many prisoners in Latria, put there by the possessed old man. Rydell is a phantom in great desperation to retrieve a precious artifact from his corpse. It is said that he is sometimes referred to as “Little Allant,” causing great speculation about his connection to both the King and Ostrava.
is sister to Garl Vinland, Maiden Astraea’s bodyguard. She ventured into the Valley of Defilement in hopes of finding her brother, but has taken refuge in the swamps unable todiscover his whereabouts. It is from her that the player learns of the Valley’s wretched past of being a dumping ground for aborted children.
-is Maiden Astraea’s loyal bodyguard and companion, and speculatively, a lover as well. He followed Astraea into the Valley to carry out her will of bringing peace to the suffering. Heprotects her with his life and has gone to great lengths to keep himself and her safe from pillagingadventurers. It is said that Maiden Astraea discovered the truth about God’s existence - or lack thereof - and thus explains why she accepted the Soul of a Demon in order to ease the troubled abandoned. Hers is ironically referred to as the most impure Soul. Yet still, Garl will never leave her side.
-is a mysterious man encountered in the Shrine of Storms whose primary goal is to find the legendary katana known as the Magic Sword “Makoto,” named after a giant in a distantcountry. His demeanor is that of one who cannot be trusted, and if given the blade he so desires, his intention may not be to let the player leave his sight alive. Little else is known about him.
Alfred, Metas, and Oolan
-were the heroes of Boletaria and the King’s most prized warriors. When the deep fog settled in, Alfred was transformed into the Tower Knight, Metas into Penetrator, and Oolan, including his army, into Phalanx. While the game engenders Oolan as a Male, the player encounters a female black phantom archer in 1-4 among the black phantom representations of Alfred and Metas. One can assume, then, that she is simply a symbol of Oolan’s army-at-large, and not Oolan himself.
-are the only two blacksmiths in the game able to repair forge weapons for the player. They once lived in the Stonefang region, and Ed still operates from within the tunnels. Legend states that an old hero nicknamed the “Legendary Big M” established his reputation when he punched a dragon to death, and in his honor, the “Hands of God” were crafted. Blacksmith Ed drops these weapons if killed.
-is a widower whose family was killed during the setting in of the deep fog; his wife and daughter were either slain or turned into Demons, but Thomas, unwilling to dwell on the past, has made his home in the Nexus and is willing to store any and all items the player is carrying.
-is a non-traditional merchant that can be found, though never visibly seen, in Shrine of Storms. Approaching the tree in which she’s perched will trigger her dialogue, allowing the player to trade items to her in return for something usually of higher value. It’s interesting to note that one of the items you can trade to her is the Phosphorescent Pole, which - as is discussed in the “Artifacts” section, is an item that Lord Rydell infamously stole from the “Witch of the Sky.” Speculatively, the Crow may very well be this Witch.
Soulbrandt and Demonbrandt are two Royal treasures of the Allant family dynasty. It is said thatKing Allant favored Soulbrandt more because of its innate connection to the dark side of human existence. Its power rose the more demonic one’s soul became, while Demonbrandt’s power increased the more pure one’s soul became.
Northern Regalia is a Boletarian weapon of ancient folklore that was said to possess immeasurable power to any and all that wielded it. Few have ever seen it, but rumor has it that the Old One has kept it in existence for malicious intent. It casts two separate shadows when in light: one of Soulbrandt and one of Demonbrandt.
Monk's Head Collar are the golden garb once worn by Latria’s possessed husband. They arethe very demonic entity that enraptured the old man and manipulated him into bringing the Latrianlands into disarray. They have found a new host in a spry, young adventurer whose thirst for soulsis as great as the old man’s once was.
Large Sword of Moonlight was a divine weapon wielded by famed Boletarian hero, the Moonlight Knight Bito. He was said to have ventured into the Valley of Defilement, too foolish to stay out of harm’s way. His remains were never found but rumors spread that his sword still lies hidden deep within the bog. It is one of the few Revelations from “God.”
Istarelle is a divine weapon wielded by famed Boletarian hero, the Holy Knight Lizaia. Like Bito, she entered the Valley ignorant of its true dangers and was never seen again, though her weapon, too, remains hidden somewhere deep within the wretched underbelly. It is also one of the few Revelations from “God.”
Adjudicator’s Shield is a lightweight shield carved with a depiction of the Adjudicator of pagan myth and an inscription that states the following: “Cowardly acts and the eating of birds must not be the deeds of the Hero of Storms. If the one being judged displeases the Adjudicator’s master, the Golden Crow, the deceased will be gnawed upon until nothing but their bones remain.”
Stormruler is a famed weapon of the ancient Shadowmen that dwelled on the Shrine of Storms. It is said to be able to rend the skies in two. Its power has diminished greatly since its creation, but perhaps amidst the resting ground for the ancestral spirits, its potential will return.
Large Sword of Searching is a weapon named after the Old Hero, who is also sometimes referred to as the “Searcher of Storms.” This weapon is said to endow the wielder with a wealth offortune in obtaining more treasure.
Bramd is a magnificent and dreadfully enormous hammer, one of the Vinland family treasures, and is wielded by Garl Vinland in battle. Its unusual shape is said to be the mark of an old giant killer.
Blind is a small, lethal curved sword carried by Selen Vinland, the blade is illusory and the weapon as light as a feather, enabling it to pass through an enemy’s shield. It is one of the Vinland family treasures.
Dark Silver Shield is made from one of the oldest known metals in existence whose properties are said to protect the user from magic. It is the symbol of the Vinland family legacy.
Talisman of God and Talisman of Beasts are two ornamental talismans used in the casting of Miracles and/or Spells. Both are supposedly crafted in the image of God and the Old One, the former a speculative misrepresentation of the latter.
Miridian Hammer is a divine weapon favored among priests, named after Mird, an area now longlost where the first temples were built.
Phosphorescent Pole is one of Lord Rydell’s most prized treasures, received during his infamous exploits of thievery from the witch in the sky.
Geri’s Stiletto is a magically-enchanted dagger given to Sage Freke and made by Geri, a close friend of his. The weapon’s properties allow it to sap a victim dry of magic.
Rune Shield and Rune Sword are a matching set of golden, ornate armaments usually given to the highest order of Knights. Ostrava is equipped with each.
Morion Blade is a weapon forged from the marrow of the Storm Beasts that soar over the Shrine of Storms. They increase the wielder’s strength as he draws closer to death, symbolic of the Beasts’ pleasure in bringing on one’s peril.
Dragon Bone Smasher is a mighty blade of pure iron forged by the ancient burrowers of Stonefang Tunnel and used to fight off dragons that threatened their excavations.
Hands of God are gauntlets honoring a famed hero known as the “Legendary Big M” who was said to have punched a dragon to death. There are rumors about Blacksmith Ed being this man.
Ring of Great Strength was a prized ring given by King Allant to each member of the Royal Twin Fangs.
