Before the king become Cult's puppet, he did one final act; he took possession of the "Ring of Succession", which was actually the key to the "Black Rose", then he recorded his last will and testament in the ring along with all evidence of Doem and cult's crimes. Also, he altered the ring to transfer control over his daughter and by marrying her is the only way to gain dominion over the Ring. After that, the king hid the ring from the cult.

Perv also told his superiors that as long as the cult holds the royal family, Rose won't be able to stay hidden. Plus Oriana's situation is already at chaos with the loss of their king, Perv is sure that Rose can't ignore it and will definitely come back.

Mordred tells Perv to taking care at Oriana Kingdom's business first, while waiting for a news about the "Ring" hiding place and postponing search for Rose Oriana for the time being. Also, Mordred hope to Doem not to disappoint him too much, before he goes to the meeting with his fellow Rounds finally decide to get serious about crushing Shadow Garden considering the destruction of the Sanctuary at Lindwurm.

Mordred found the "Ring" hiding place, which is the Saisho Stronghold. Then, he ordered Doem to retrieved the ring first by bringing Queen Reina along with 40 First Children, led by 4 Named Children, among them is Kouadoi.

Oriana's "Black Rose" Civil War Wedding Incident
After hearing the news that Doem had obtained the "Ring of Succession" and Princess Rose, Mordred immediately prepare to pulled all the necessary strings for his 12th seat position, which he promised to Doem. Before the wedding, he telepathy contacting Doem and congratulate him by telling him that the preparation have been completed and expect great things from him and not to let him down, which he replied yes, unbeknownst that the "Ring of Succession" have missing.

During the wedding after Rose activated the ring and then a recording of the king's projection had appeared with the information that exposed the Cults' crimes and defeating Doem, Mordred decided to reveal himself after killing Doem Ketsuhat and Queen Reina for just a little cleanup, also opens the now unlocked "Black Rose", letting loose hordes of Magical Beasts upon the capital in order to kill everyone in Oriana so that the cult can take control of what's left of the kingdom. Shadow Garden then make their move to suppress the outbreak and two "Seven Shadows" Epsilon and Beta confronting Mordred to check "their answers on a few things" before they kill him.

Mordred don’t have time to waste for them and he pulls something from his pocket and hurls it into the Black Rose to summons Ragnarok, Grand Ruler of the Fourth Realm. Suddenly, Shadow appeared and cut one of Ragnarok’s wings. Mordred begin to praised him for his sudden strike and mock him that he angered Ragnarok, before Shadow cutting him off and mock him back and he begin fighting against Ragnarok to the death outside the capital.

While Shadow fights Ragnarok, Mordred fight against Beta and Epsilon in the triangle position. Then, in the blink of an eye, Mordred decide to strike at both of them before they leap backward at the same time, only able to wound the legendary Faithful, Epsilon. Mordred compliment them for dodged his strike until Beta revealing his secret, which is the Invisible Sword from the long-lost elven artifact. He mocked them for trying to retrieve the sword before Epsilon suddenly strike him down by throw her magic, much to his shocked.

Mordred felt twist in humiliation after fighting two Seven Shadows, only for him to be struggle. After that, Mordred decide to ending the fight and having conversation to them about checking their answers of the "Black Rose", the magical beasts and Diablos at his confident that Ragnarok will defeat Shadow. Mordred telling them started at there are countless other worlds beyond their own world in entire other dimensions, which he call it Realm. With the worlds orbiting around and spin as the years go by until they collide, which the impact sends rifts across the worlds, with two different worlds become linked and each exerts influence on the other.

Even Mordred says that this world has no magic and human are not the original inhabitants, because this world making contact with Realm in another world and the Cult’s are doing research for their working theory that this world and the Realms interact with each other on a cyclical basis and exerts influence over each other. Beta questions him whether Diablos also came from one of these other worlds. However, he claimed that her assumption was false and that Diablos was a genuine inhabitant of their world and telling her that the demon isn’t true of the original Diablos, which is the organism that became the basis for Diablos and theorize that Diablos called the original in from the First Realm which is higher than the Fourth Realm. Then, Mordred checking both Seven Shadows last answer about the "Black Rose" which Beta confirm that it’s a gate that can connect to this world to Realms.

Mordred’s praise them for their correct assumption about the "Black Rose" and telling the real story of the "Black Rose" when accidently open also poured magical beasts at Oriana Kingdom during the siege of Velgalta Empire, which was a stroke of misfortune for both nation. Even with the Velgaltan soldiers dead, the gate still kept summoning magical beasts and began to consuming Oriana and the Kingdom would have been quite literally obliterated, if a certain someone hadn’t stepped in and closed the gate. Due to this, When Beta said that it was after that time when the Cult of Diablos decided to make the Oriana Kingdom into their puppet, Mordred replied that the cult were the ones who closed the gate and saved the kingdom with the cult stewardship of the Black Rose to ensured that the kingdom would survive in perpetuity if the kingdom give the cult a fair compensation, which is the Royal Blood.

Mordred tell Rose Oriana that It was her blood that the cult wanted, which even for a royal that she blessed with incredible amounts of magic and as their agreement, the kingdom should have turned her over to the cult when she still a baby. But his father, the king foolishly refused them. Beta also adding that the Cult compensation not only a royal blood for kingdom to demanded. The other compensation is that the kingdom were to give a majority of their tax revenue to the cult, resulting in the kingdom to heavily invest on the arts was so it could entertain them. On top of that, the cult are manipulating the church to persecuted Dark Knights as a way for the Cult to prevent Oriana from gaining the strength and no manpower to rebel against the cult, which basically became a puppet kingdom. Beta tell Rose that the King wanted to break the cycle by forged an alliance with Midgar Kingdom, in order to fix his twisted nation from within, and tried to secede from the Cult, but they killed him and confirming the reason Rose allowed to study at Midgar Academy is to get her somewhere safe from harm.

Mordred calling Rose's father, the king as a fool and telling him that with the gates of the "Black Rose" still open, the Cult will take direct control of the Oriana Kingdom. However, Rose Oriana, who hates the Cult, will not let that happen and will continue her father's cause by rebuilding her kingdom with her own hands. He laughs at her statement and wish that Oriana Kingdom will burn to the ground by Ragnarok until suddenly a Ragnarok's right arm fell at the place Mordred fought against Beta and Epsilon, hitting his left arm.

Noticing this arm, Mordred still believe Shadow can't bring down Ragnarok when a Ragnarok's body parts flying one after the other have been gather at the same place, much to his surprise. Beta calling him a fool because Shadow had him dancing in the palm of his hand this whole time, and add every pieces clue of the many Shadow Garden forces being gathered here, the "Black Rose" reaction and how did Rose Oriana have the "Ring Of Succession" which is the key of Black Rose.

Mordred now realized that Shadow knew everything from the very start and wanted to observe the cult's movement until he plans on destroying the Black Rose in its entirety, also saw Ragnarok's remains fell in front of his eyes along with Shadow. Mordred become disillusioned about the power of Shadow Garden is so much stronger than the Fourth Realm itself. Then, Mordred hollow laugh escapes from his throat because the outcome and decide to consuming Ragnarok’s flesh, absorbing it's power until his body begin to change and strike Shadow with his upgrade power form.

Shadow seeing Mordred state by telling him as an failed experiment and taunt him that Ragnarok was stronger than him also mock him about merging with too much power without intellect, much to his frustrated anger. While Shadow was still looking at the sky with his back to Mordred saying the darkened sky heralds the end and hearing the nascent monarch’s cry to Mordred, Shadow powerful magic began gathers at his right hand.

When until his magic finally gathers at his obsidian sword, spiraling through the air and drawing an elaborate pattern over the weapon’s blade. Mordred could only shocked of his magic which no human could have possibly possessed this massive power before Shadow kills him with his Atom attack.
