Death Upon Us All

In the deepest fractures of the Celestial Realms, beyond even the knowledge of the Eternal Kinmas, lies an ancient force known only as The Abyssal Choir - a forgotten order of fallen celestial entities once cast out by the Prime Star. After a millennium of silence, their cursed symphony echoes again across the cosmos. With it comes the death of light... and the unraveling of fate.

When entire constellations begin to bleed, and starborn worlds collapse without warning, Kei - now a Celestial Vanguard in her sixth form - is summoned by the Celestial Tribunal to investigate the disturbance. Alongside her allies - Teri, Akira Kazehaya, Esme, Jackson, Solara, and the reborn Nova - they journey into Nyxetherion, the forbidden 13th realm buried beneath time and stardust.

But what they discover is a terror beyond even the Kinmas' comprehension. The Deathfather, a divine entity erased from the scriptures, has awakened. His voice carries a curse that erodes the very souls of gods - and his goal is simple:

To end all existence so that silence may reign eternal.

As truths about their divine heritage surface, and allies begin to fall to corruption, Kei must confront the terrifying possibility that her power-her very creation-may have been part of the Deathfather's plan. And in the heart of Nyxetherion lies a paradox:

One of them must accept death as its new god to save the cosmos.
