Oscar Orcus/Chronology

History
Oscar was an orphan from the Kingdom of Velka. He was abandoned as a baby and was taken in by Moorin at her orphanage. At the age of 10, Oscar discovered his abilities as a Synergist after the orphanage's sponsor, Karg D. Verand, visited it. Oscar witnessed Topp use his own Synergist skills to repair a broken plate and tried to imitate what he saw him do. From then on Oscar crafted many toys for the other orphans. Topp would eventually see the new toys that Oscar created and was very impressed by their quality. He decided to take Oscar as his apprentice and employed him at his workshop. Though Oscar was a very skilled craftsman, he never made anything more that common everyday items for Karg, as he was afraid to stand out too much if he used his skills to the fullest.

"Zero" Timeline
In Volume 1, Oscar was working at the Orcus Worship when he was being bullied by another craftsman named Ping Waress and his two friends Torpa Parson and Raul Streya. Ping was also having Oscar do his work in addition to his own and demanded that he do an incredible job on the work he claimed he was giving him as a way to help improve his skills. Just then Karg intervened by claiming that the workmanship on Oscar's pieces was excellent, despite them only being common items. After Ping and the others fearfully retreated back to their own work stations, Karg sternly invited Oscar into his office and asked him why he didn't show his true talents as a craftsman. He felt that Oscar was far more talented than him at this point and did not feel that he deserved to be treated much better than he was. Oscar happily claimed that despite the ridicule he frequently faced, he liked his job and the type of items that he crafted. Just as Karg was about to claim that Oscar had already surpassed him as a craftsman, Oscar stopped and told in a most serious tone that his skills were so impressive that they were considered abnormal, much to Karg's surprise. Oscar then reaffirmed that he liked his job and would continue working for him, to which Karg begrudgingly accepted. Oscar then headed out to deliver some of his work orders, to which Karg told him to take the rest of the day off in order to check up on his old orphanage due to the reports that children mysteriously disappearing.

After finishing his work for the day, Oscar was checking up on Moorin's, as well as examining the hidden defense systems he had previously made. Once he entered the building, he wasn't able to find anyone inside. After frantically searching for them, he was greeted by a mysterious girl named Miledi who was cooking dinner in the kitchen while making passes at him, Oscar was about to kick her out when the orphanage's children suddenly appeared from various hiding spots and claimed that she was actually their guest. As everyone was having dinner, Moorin cheerfully explained to Oscar that them disappearing was just to prank him and apologized for scaring him. The dinner conversation shifted to most of the children bragging to Miledi about how great they thought Oscar. However one boy named Ruth instead instead harshly criticized him to the point of calling him a loser. Moorin immediately demanded that Ruth apologize to Oscar in a various serious tone, but he refused to do so. Another orphan Dylan also tried to stop Ruth from insulting Oscar, but he refused to listen to him as well. Miledi then stood up for Oscar by claiming that he was actually an incredible talented person, as well as being the reason for her visit. Taken aback by Milidi's sudden declaration, Oscar asked why she wanted to see him, but she only responded with remarks that was annoying him, and had even jokingly accused him of not wanting to be with be because he wanted to marry his foster sisters Corrin and Katy. This utterly infuriated Oscar and he kicked Miledi out of Morrin's home. As her tossed her out, Miledi managed to magically reorient herself and landed on he ground without any issues. Once the two of them were alone, Oscar asked Miledi what she wanted with him. At first, Miledi continued to act in a easing manner, but soon got serious and explained that she had be traveling from town to town in search of people with special talents, and that she heard of Oscar being a talented craftsman while visiting the Velka kingdom. Oscar tried to brush off these tremors by claiming that he was just a Synergist, but Miledi argued that no normal craftsman could create anything on Oscar's level after seeing the powerful magical defense systems he created for the orphanage, and eve went so far as to clarify them as Artifacts. Hearing Miledi's analysis of Oscar caused hm to become more wary of her and glared at her intensely, but Miledi claimed in a genuine tone that she just wished to talk with him. At first, he thought Miledi wanted him to make her powerful Artifacts, but she rebutted by saying that it would up to him on what he wanted to make, then immediately gone back to her teasing side and used Oscar's suspicious as a way to accuse him of being a masochist. An irritated Oscar resounded by activating one of the orphaned defences and electrocuted her. Once that was over, Miledi once again spoke in a serious tone and said that she wanted Oscar to join her on her crusade to change the world that both of them saw as being controlled by the Holy Church, and that Oscar was afraid to reveal his talents because he was afraid of both him and his family being controlled by the church. Miledi then revealed that she was part of a group called the Liberators that sought to free the world form the control of both the church and the gods that they worshiped. Oscar, however, refused Miledi's offer and asked her to leave him and his family forever. Miledi decided to take off and asked Oscar to thank his family for dinner. Once she was gone, Oscar though about how he would never have o see her again.

The next day when Oscar was at work, Miledi should ups unannounced and asking for his name. Oscar was so shocked to see her once again that he hid beneath his works station in order to avoid her seeing him. Oscar's co-worker Ping attempted to curry favor with her, but Miledi was uninterested and resumed her search for Oscar. After she found him hiding, Miledi expressed her delight of seeing him once more since the night before. This statement immediately caused the other craftsmen to suspect that Oscar was romantically invalid with Miledi. Before she could say anything else, Oscar escorted her away while pretending that she was one of his customers who was picking up an order. He had her accompany him while he was preparing to make deliveries to his actual customers and threatened to punish her if she refused though his facial expressions, which she agreed to do. As the two headed out, Oscar accused Miledi of lying to him of leaving him alone for good, but Miledi argued that she never actually agreed to Oscar's request and vowed to follow him until he agreed to join her on her mission. Oscar, however, remained adamant of refusing Miledi request and resumed his job while being accompanied by Miledi (much to his annoyance).

After Oscar finished all his deliveries, he and Miledi headed to his favorite restaurant for lunch. He was exhausted after having to put up with Miledi's antics during his travels. Soon they were approached by the restaurant's waitress Aisha. As she greeted Oscar, she saw Miledi sitting beside him, and immediately mistook her as his girlfriend. Oscar and Miledi tried to correct her assumptions, but Aisha was too distract due to having a crush on Oscar and ran away crying while giving their lunch order to the chef (who was also her father). Afterwards they were approached by two of Oscar's adventurer friends Failur and Scurdy and teased him about having finally found a girlfriend. Oscar attempted to clear up the misunderstanding, but Miledi told them that she was still working on making Oscar her's (much to his detriment). The two adventurers then approached a more serious topic and warned Oscar about having seen his co-worker Ping and his friends skulk around his neighborhood night where children were recently known to have disappeared. In addition, they noted how these recent disappearances coincided with an increase of activity from the church's templar knights in the kingdom's mines. The two of them then said their goodbyes to Oscar just as his meal was being delivered. Before he was about to eat, Oscar saw Miledi with a usually serious expression on her face, and called back to back to reality before they ate their lunch.

Once they finished their meal, Miledi decided to take off once more, but asked Oscar if she could visit a work the next day. Realizing that she would visit him regardless, Oscar resined himself to having Miledi follow him around. Over the next week, Miledi continued to follow Oscar while he was at work. It had become such a common occurrence that the townspeople were used to seeing the two of them together. Even Oscar became more accustomed to having her around and engaging in more conversations with her. One evening as he was once again heading to his old orphanage, Miledi approached Oscar and greeted him her usual over-the-top tone. Oscar had decided at that point to severe all ties all ties with Miledi for good. However, before he could say anything, Miledi asked him in a serious tone to speak with him about something, to which Oscar obliged her. Miledi revealed that she was actually the heir to the Reisen family from the Grandort Empire that were known for executing heretics of the Holy Church, and that she joined the Liberators after a faithful encounter with one of their members, Belta Lievre, that posed as her maid in order to rescue her captured comrades. Miledi's time with Belta greatly changed her perception of the world, and ultimately decided to oppose the church after Belta's true identity was discovered, and executed for it. Oscar was greatly affected after hearing Miledi's backstory, but sill refused to join her in order o protect his family from the church's wrath. As he left, Oscar told her to never see him again. This decision greatly conflicted him, but ultimately decided it was best to not fight back against those that were oppressing the world.

After Oscar left Miledi, he resumed his trip to the orphanage. Once he arrived, Moorin suddenly approached him in a panicked state and explained to him that several of the children had failed to return home from their errands. She had previously asked the town guard for help, but they refused to comply. Moorin suspected that something very bad was about to happen based on how determined they were not to get involved. Oscar had managed to locate them at the kingdom's mines thanks to the "Silver Slate" Artifact he created that allowed him to track matching pendants he had made for them. Oscar promised to rescue the children and ordered her to barricade herself inside her home with its defense systems. As he was about to leave, Moorin asked Oscar to care of himself during his search, to which he promised, but still left her concerned for him. Oscar headed to his home to gather many of his Artifacts and headed out to the mines by using his "Oynx Boots" to left him travel their mid-air. Once he was there, Oscar used his Silver Slate to search for them, but was unable able to determine their precise location due to the many floor levels the mines had. When he’d reached the 65th floor, Oscar found the kids’ clothes, along with their coins stored in a safe, thus making it impossible for him to locate through his Silver Slate. He also saw multiple templar knights on patrol and soon sensed the usage of transmutation magic nearby and discovered that it had been Ruth attempting to escape with other kidnapped children. Unfortunatly, one of the knights saw what Ruth was trying do, and was about to kill him when Oscar arrived and knocked the knight out. Bewildered by Oscar's sudden arrival, all Ruth could do was call out "brother" to him, despite having not called him that for a long time. Oscar then noticed Ruth's earlier attempt to use his transmutation magic to escape, to which Ruth told him that it didn't work. Oscar explained that the reason it failed was due to the bars being made of a special material that dissolves mana known as "Sealstone". Oscar then managed to free Ruth and the others by transmuting the bars by pouring more mana in them than they could handle. He then approached Ruth and praised him for his earlier efforts in trying to escape since that was what lead him to the children. He soon noticed that the other children from the orphanage were not present, to which Ruth explained that they were taken away elsewhere and that he remained due to being "incompatible".

When Oscar lead the children out of the cell, he instructed Ruth the lead them out of the mines with a passage to the surface that he transmuted for them due to him needing to rescue the rest of the children that had been taken further in. As the other children headed out, Ruth stayed behind in order to apologize to Oscar for how he had previously mistreated him, but was stopped by a surprise magical attack that approached him. Oscar managed to pull Ruth away to safety before he was struck, but saw that the passageway he made was now blocked. Furthermore, the two of them saw that they were being surrounded by ten templar knights. As Oscar was prepared to fight them, Ruth didn't think it would be possible to escape, and begged him to reconsider. Oscar, however, assured Ruth that he would protect him. One of the templar knights then offered Oscar the chance to save himself if he let them have Ruth, as well as beg for his life, to which Oscar rejected the offer in a very curt manner. This immediately prompted the knights to attack him. Despite their best efforts, they were all killed by Oscar thanks to his powerful array of Artifacts. He was even able to block one of the templar knight's legendary "Celestial Flash" attacks with his "Black Umbrella" Artifact. After seeing Oscar fight first-hand, Ruth properly apologized to Oscar for how he had treated him in the past. As Oscar sent Ruth back on the path he created to the surface, Ruth told Oscar where he could find the other children based on the various minerals he remembered seeing during his time in captivity.

When Oscar arrived to where the rest of the children were being held, he saw that the members of the church were waiting for him. Among them was Bishop Forneus Abyssion, and had even taken his foster sister Corrin as a hostage. It was revealed that Oscar's co-worker Ping and his two friends were conspiring with the church and had the children of the orphanage kidnapped due to his grudge with Oscar. I was also Ping that warned the church's forces about Oscar after seeing his previous battle wih the templar knights. Realizing how his inaction lead to the kidnapoing of his family, Oscar was immediately prepared to attack. Forneus attempted to stop Oscar by grabbing Corrin and threatening to harm her, but Oscar managed to rescue the young girl while also knocking him and his knights away. Oscar easily dispatched the knights and forced Forneus to reveal the location of the kidnapped children, to which the bishop told him that they were inside the building that he had constructed within the mine. As Oscar was about the enter it, he was stopped by several of the kidnapped children that had somehow been turned into mindless warriors. Oscar managed to hold them off, but was injured after he was attacked by two of the other children from the orphanage, Dylan and Katy. Oscar tried to hold them off, but eventually surrendered after seeing that they would strain themselves to death from all the fighting. Forneus then approached Oscar and commended him for his skills, as well as the Artifacts he used. He offered Oscar a chance to join the church in exchange for the safety of the children and returning them to normal, to which Oscar reluctantly agreed. Corrin sadly begged Oscar to not give up, to which he merely smiled at her and assured her that everything would be alright.

As Oscar was about to swear his loyalty to the church, he was stopped when Miledi suddenly appeared from inside the roof of the building by using her Gravity Magic. She then used it to reveal the Artifact that Forneus used to transform the children, as well as revealing that he had no idea to the reverse its effects. Forneus ordered Dylan and Katy to kill themselves in an attempt to motivate Oscar to fight for him, but they were stopped by Miledi by using her gravity magic to knock them out and gave them to Oscar. He then angrily ordered his forces to attack Miledi, but she managed to ward off their spells with her magic and proceeded to crush all them of by significantly increasing their own gravity. In a last ditch effort, Forneus tried to bombard Miledi with a barrage of boulders with the spell "Earth Blast", but she too managed to crush them by redirected the attack at the church's forces.

Miledi then approached Oscar as he was healing himself using a feature from his Black Umbrella Artifact that rained healing magic on him. She praised Oscar for having such a creative feature. Oscar then asked Miledi how she found him to which Miledi revealed that she had followed Oscar in secret and used her magic to punch her way into the floor below in order to launch a sneak attack against the church's forces. Oscar asked why Miledi didn't just approach him from the start, to which Miledi explained that she didn't want to upset Oscar after he told her to leave him forever during their last encounter. Hearing the prompted Corrin to scold Oscar for how he treated Miledi and demanded that he apologize to her. Miledi immediately expressed her amusement of Corrin's treatment of Oscar in that moments, and while Oscar still believed he had done the right thing in told her to leave him for good, he sill thanked her for her help.

They were soon interrupted by Bishop Forneus, who despite the severe injuries he sustained from the battle,was still alive, albeit horribly disfigured, and proceeded to proclaim to Oscar and Miledi that they would feel Ehit's wrath. He was then killed when Oscar threw a needle at his forehead that was accelerated by Miledi's Gravity Magic. Despite their efforts, however, Forneus managed to use the last of his mana to cause a cave-in by self-destructing his body. Miledi managed to keep the crumbling cave roof at bay with her magic and told Oscar to escape with the children, but not before letting him use his magic to enchant he church's Artifact so that it could survive the cave in for him to retrieve later. While the two of them were distracted, Ping, who Oscar had imprisoned during the battle with the templar knight while trying to escape, managed to free himself by using a hidden knife that was under his sleeve. He then attempted to kill Oscar, but was suddenly killed when a giant ball of fire struck him that came from a three-headed earth dragon that was guarding the church's Artifact. It then went on a rampage and flung borders towards the cave's entrance (which also killed Tarpo and Raul while they were fleeing), and followed up by attacking Miledi with its flame breath. Miledi once again told Oscar to escape with his family, but Oscar instead decided to stay behind and help her by repairing the cave sealing so that she could focus on destroying the dragon. Miledi objected since that also meant destroyed the Artifact and ruining his chance to save his siblings from its effects. Oscar, however, believed that ensuring Miledi survival was the best chance of saving everyone. After receiving some encouragement from Corrin to support Miledi, Oscar transmuted a makeshift gandola o protect he kids and headed off to help Miledi.

Oscar transmuted the cloth of his umbrella off its frame and turned into a multitude of metal strings, which flew up to the ceiling. Then, he used remote transmutation to make sure they stuck to the ceiling where they landed. As Oscar levitated up to where Miledi and Miledi headed down towards the dragon, he had the rest of his umbrella self-destruct right on top of the dragon's head in order to give Miledi a fbetter chance at killing it. As the two briefly passed by each other, Oscar gave Miledi a small jewel that had been embedded into the umbrella’s handle hat he took out before throwing it. Once they arrived at their destination, Oscar repaired the ceiling almost insanely while Miledi obliterated the dragon completely, as well as the Artifact, with her gravity spell. "Nether Burst". However, the strength of her magic also created a gigantic pit in in he mines' floor, much to the shock of both of them. Miledi blamed Oscar for what had happened due to the increased power she received from the stone he gave her. Oscar explained that it was actually a Divinity Stone that he made over the course of six years. He then asked Miledi to return it to him, but she had accidentally dropped down the giant hole she made due to how surprised she was at the amount of mana it had supplied her with. At first, Oscar was upset over the revelation and glared at Miledi for her blunder, but soon got over it and was happy that they rescued his family.

Two days after Oscar and Miledi rescued the kidnapped children, he and his family decided to leave the kingdom for their own protection. Morrin and the orphans were taken in the Liberators for their protection. Unfortunately Dylan and Katy remained unconscious and could not be healed through normal means. Before Oscar left he visited the Orcus Workshop once more to deliver his farewell letter to Karg before the store opened. To his surprise, however, Karg and the other craftsmen were waiting for him when he arrived. As they said their goodbyes to each other, Karg asked Oscar to honor his last request and accept the "Orcus" name for himself, to which Oscar happily agreed to.

Once Oscar finished his goodbyes and departed from the kingdom, her headed down its main road until he met up with Miledi, who was waiting for him. After greeting each other, Oscar decided to accept Miledi's request for him to join her on her mission out of gratitude for saving his family. Miledi, however, was uninterested in have Oscar be indebted to her, and expressed her to have him accompany her of his own free will. Int that moment, Oscar was encaptivated by Miledi, but soon came back to his senses and vowed to follow her even into Hell. Contrary to Oscar's serious declaration, Miledi instead teasingly expressed how creeped out she was as how much he had apparently fallen for her. Oscar was overcome by a flurry of emotions and began chasing after Miledi with firing a series of magic attacks from hiss umbrella. Even so, the two of them set off on a new journey together.
