HISTORY

Cecilia was a famous singer and song-writer who worked under the name "Cersea", but she suffered from PTSD following the Fall of the Old Capital, which made her unable to sing despite the numerous songs she wrote at the time. Her agency forced her to continue her work, as her singing could help alleviate the hopelessness felt by the people following the catastrophe. They found a voice double for her, the Intelligent Construct Aria, who had been awoken from her slumber in a Hollow due to hearing Cecilia's music, and they began working together. Aria stood in as Cecilia's voice for her last few shows before she retired from performing, but she felt terrible about the situation, and believed that Aria should be able to succeed on her own, without being stuck in her shadow.

As time went on, Cecilia recieved treatment for her PTSD, Aria's singing helped her recover. She also became friends with Astra Yao at some point. Her appearance and voice changed, and she eventually came to meet the Angels of Delusion, which Aria was part of. She signed on to be their vocal coach, though due to her lingering guilt over having Aria work as her voice double, she withheld her former identity as Cersea from the group. She also came to take over 404 Error, offering invitations to various groups such as Satellite, The Forecasters, The Darkforge and The Deepsea Aliens.

In the lead up to the Gilded Carrot Day that followed after Ye Shunguang was awarded the title of Void Hunter, rumors circulated that Cersea would come out of retirement, but Cecilia had no intentions of returning, with Vesper - a singer from TOPS Entertainment, taking the role of lead performer instead. The intelligent entity Youkai began causing problems throughout New Eridu by hijacking construct citizens, and it was during this time that the truth about Cecilia's identity was revealed, causing Aria, who was already under emotional duress and suffering from Youkai's influence, to spiral and was hijacked in turn.

After she recovered, the master-student-pair came clean to one another, reconciling before continuing their preparations for their Gilded Carrot Day performance. However, Youkai had managed to coerce Vesper, hoping to use her to disrupt the celebrations. After Aria overcame Vesper in a co-op encounter, she was taken away by Krampus, leaving the staff for the ceremony desperate for someone to take over, and returning to Cecilia. She proposed to the Angels for them to join her on stage, but they refused, not wanting to compromise their debut performance at the 404 Livehouse. Expressing her pride in them, the angels returned to Sixth Street, while Cecilia took the stage to perform at Failume Heights, singing the same song as the angels as they welcomed the new year.

Cecilia currently living in "New Eridu"

New Eridu:New Eridu is a vibrant, neon-drenched cyberpunk metropolis that stands as humanity's final bastion against the world-ending threat of the Hollows. It is a city defined by an intense contrast between retro and futuristic technology, where street-level VHS repair shops, cozy ramen stands, and arcade culture sit right alongside advanced robotic Thiren citizens and high-tech industrial mech suits. The entire city's survival and booming economy are fueled by Ether, a volatile but incredibly valuable resource extracted directly from the apocalyptic anomalies right outside its borders, creating a high-stakes society split between glamorous corporate districts and the gritty, danger-close reality of the outer street blocks

World building:humanity has been pushed to the brink of extinction by "Hollows"—chaotic, shifting spatial anomalies that swallow cities and mutate anything inside into monstrous Ethereals. This global apocalypse reached its peak during the tragic Fall of the Old Capital, a catastrophic collapse that wiped out the world's original metropolis and forced the survivors to flee. From those ashes, humanity built New Eridu, a retro-futuristic sanctuary that paradoxically thrives by harvesting the highly valuable, corruptive "Ether" energy from the very rifts that threaten to destroy it. Now, playing as the legendary, underground Proxy duo Phaethon, players guide diverse Agents through these dangerous spatial zones, caught in a high-stakes struggle between corrupt corporate elites, ancient sects, and the ultimate truth behind the world's survival**.**

THE FALL OF THE OLD CAPITAL:

Eleven years ago, the prosperous metropolis of Eridu was devastated by an unprecedented catastrophe known as the Fall of the Old Capital. In a massive spike of activity, the destructive spatial anomaly known as Hollow Zero expanded exponentially, quickly consuming the city's wealthiest and most critical districts, the Pluto and Minerva Quarters. The Eridu Defense Force suffered catastrophic casualties trying to contain the sudden outbreak.

​In a desperate, last-ditch effort to halt the apocalyptic expansion, the city's leadership made the brutal strategic decision to detonate 14 Shiyu Towers along a major southwest-to-northeast axis. This intentional explosion tore a massive chasm straight through the city. While the act successfully starved Hollow Zero of the material it needed to corrupt and grow—effectively containing the blast zone—it reduced the vast majority of the original city to absolute ruins and displaced millions of citizens. The survivors who pulled themselves out of the wreckage went on to build a new life nearby, reshaping what was left into the modern refuge known as New Eridu.

Angels of delusion:

Aria (Center / Main Vocalist): The bubbly, energetic pink-haired leader of the group. She has a bright, fiercely optimistic "classic idol" personality and acts as the public face of the trio. She possesses an incredible singing voice, which heavily ties into the faction's backstory and Cecilia's past.

​Nangong: The group's moody, gothic-inspired member. She sports black hair with bright pink highlights and wears an edgy, alternative outfit complete with a dark halo accessory. She brings a sharper, cool-headed, and somewhat cynical attitude to the group's dynamic.

​Sunna: The relaxed, green-haired member who rounds out the trio. She has a much more laid-back, sleepy, and effortlessly casual vibe compared to the high energy of Aria and the sharp edge of Dorothy, often bringing a calm presence to their chaotic idol life.
