It looks like our battle is about to begin.

Isolde is a commission-exclusive NPC who appears in Season 2: Chapter 2 and Chapter 3.

Profile

Isolde was an officer who served in New Eridu Defense Force with the rank of colonel. She helped Phaethon reveal the collusion between Ferox and The Exaltists.

History

Prior to the Fall of the Old Capital, Isolde was a member of the Obsidian Division's Agamemnon Squad, leading as its Captain.

During the expansion of Hollow Zero, Isolde and her squad-mates, notably Orpheus, were deployed in the vicinity of Waifei Peninsula, being tasked with defending what they believed to be a train carrying civilians out of the Hollow. The squad eventually came under heavy assault from miasma-spawned Ethereals, with many of them being injured and later perishing in the skirmish. Yijiang, 12th High Preceptor of Yunkui Summit and Yixuan's sister, came to their rescue, allowing Isolde and a heavily injured Orpheus to escape.

After some time, and after Orpheus' passing, Isolde would begin to question the orders she had received back then, and would begin to investigate matters by herself. During this investigation, she would become acquainted with Aitana and her son Dante, as Aitana's brother Maxim, another Defense Force soldier, had also perished during the various skirmishes of the fall. Isolde claimed to have retired from the Defense Force, becoming a research consultant of the army, though she secretly retained her position as colonel.

Despite gathering as many old case-files as she could, Isolde was unsure whether there was enough concrete evidence to lead to a conviction of those who she believed had committed crimes during the fall, as she had long-since given up on New Eridu's authorities. Instead, she decided to keep digging deeper by herself, which caused her to make contact with The Exaltists nder the name Mevorakh, leading her to move between the Defense Force, the Exaltists, and Porcelumex, playing each side in turn.

Eventually, Isolde would uncover the truth. Lucro, one of the co-CEOs of Porcelumex, had bribed Lorenz, who later became Major General of the Defense Force, into redeploying troops that were meant to protect the citizens, in order to recover valuable Porcelume stockpiles. In short, the train that her and her comrades had been willing to sacrifice themselves to protect, had not been carrying civilians as they had been told, but rather valuable assets such as Porcelume.

When Landon died, she relocated many of the Janus Quarter Exaltists in Waifei Peninsula, where they signed a partnership with Ferox to get Porcelumex's funding and protection in exchange of Exaltist tech obtained from Sacrifice research. When the previous Overseer died, Isolde was chosen by the Creator to inherit their power. She thus gained the authority to command the entire Exaltist organization, while the power of the Miasma she had inherited slowly seeped into her body, eating it away from the inside. She also used her newfound authority to publicly declare that the Creator would not mold unwilling subjects, and rejected Porcelumex's proposal to continue human experimentation.

Despite her time running out, Isolde would continue to orchestrate her revenge plan, swapping between playing sides as Isolde herself, or Mevorakh as needed.

As Mevorakh, she had been the one to stir-up Miasma anomalies in Lemnian Hollow, corrupting Failume Heights residents in order to make Yunkui Summit return to Waifei Peninsula. By doing this, she had managed to confront Yixuan and retrieve her memories of Yijiang, the previous High Preceptor, using them to create an Ethereal monster that resembled Yijiang.

As Isolde, she attended the banquet held by Porcelumex to welcome the inspection team from TOPS and other organizations, showing up as a research consultant of the army. She then secretly followed the team led by Ukinami Yuzuha, and headed to Sailume Bay to investigate the Obscura Fragment. Eventually, she would uncover collusion between Ferox, the other co-CEO of Porcelumex, and The Exaltists, that she herself had set up as Mevorakh, eventually leading Obol Squad to rescue Yuzuha, who had been trapped in the Porcelumex laboratory, and to arrest Ferox, stopping him from destroying the evidence by detonating Ether dynamites.

Although her revenge plan was making headway, Isolde would gradually lose the right to prevent the situation from spiraling further out of control. When all the key figures in her plot were finally in her grasp, with the Porcelumex CEO Lucro and Major General Lorenz being present in Failume Heights, she would commit to a final gambit, murdering Lorenz as Isolde, while, as Mevorakh, she would cause Lemnian Hollow to spike in activity and approach the Zenless Limit, using the Miasma to spawn corrupted soldiers donning the appearance of Defense Force personnel from the time of the fall.

In her final moments, she used her Overseer powers over the Miasma to become The Defiler, but would be swiftly defeated by the combined efforts of Yixuan and Obol Squad. Then she lost a duel with Orphie and Magus. Finally, knowing that she had gone too far, she shot Orphie with a non-lethal Denny gun to tempt her old comrade, Magus, into dealing the final blow, bringing the story to a close.

Etymology

  • Isolde is an alternative spelling of Iseult, which is likely derived from the Old High Germanic words of īs "Ice" and hiltja "Battle". The name was popularised by the Arthurian legend Tristan and Iseult, which features three different characters that share the name, most notably "Isuelt the Blonde," the title character of the legend, who was an Irish princess that had an illicit romance with Tristan.
