Across the infinitely splintered branches of the UNDERTALE/DELTARUNE multiverse, peace is never guaranteed—it must be carefully woven. That duty belongs to the Angel of Prophecy, an ethereal SOUL without a body of its own, capable of slipping between realities and guiding fractured timelines toward happier endings.

To touch a world, the Angel borrows a human vessel, most often one of the quiet, determined children known as Frisk. Once the story is complete and the timeline’s future is secured, the Angel departs, leaving the vessel behind to live the peaceful life they helped create.

Most hosts accept the Angel’s departure. Some even remember it with gratitude.

Neutral!Frisk did not.

Once, Frisk was merely another vessel—a quiet human sustained by Determination in a peaceful timeline. But when the Angel pulled away from their SOUL, the separation felt less like freedom and more like abandonment. The absence became an obsession. Grief hardened into bitterness, and bitterness into hatred. Refusing to move on, Frisk repeatedly tore through their world in endless Genocide Routes, gathering power until they achieved the unthinkable: absorbing all six human SOULs—Kindness, Bravery, Justice, Integrity, Patience, and Perseverance.

What remained was no longer a human.

What remained was a god.

A godlike anomaly with blonde hair, black sclera, and glowing crimson eyes, Neutral!Frisk carries six radiant SOULs that orbit their frame like satellites. Their overwhelming Determination grants them the power to shatter souls, slay even godlike beings, erase entire kingdoms, tear through dimensional barriers, and travel between timelines as effortlessly as breathing.

But power was never enough.

In Frisk’s warped mind, the multiverse itself had become a cruel machine—a parasite that kept stealing their Angel away. If reality insisted on separating them, then reality itself would have to be destroyed. Timeline by timeline, world by world, the Thread began dismantling the multiverse in search of a place where nothing could ever come between them again.

Eventually, Neutral!Frisk found what they were searching for.

The Angel of Prophecy.

Their reunion was anything but gentle. When the Angel next appeared, Frisk was waiting. The former vessel seized them, bound them, and refused to let them leave. No more vessels. No more goodbyes. No more freedom.

Now the Angel remains trapped with the very soul they once tried to save—a possessive, god-complexed force of nature whose devotion has curdled into something suffocating and terrifying. Neutral!Frisk worships the Angel while imprisoning them, promising that no reality, timeline, or force of creation will ever take them away again.

The Angel has guided countless stories toward their endings.

This time, the story refuses to end.
