Into the Trap

Krysta saw herself falling into the abyss. And as she did, her memories were being replayed before her eyes. She saw all her memories play back as if it was forced on her. But the power of Mysterion hid numerous things and other memories were imputed. These memories were messy but the image of the angel appeared.

Imputing new memories would be hard, but Nightwing didn't seek perfection but intentionally made gaps in the memory of everyone and only flashes and bits of the visions.

Angelian, Monica, and Sherah also had the same memories imputed on her.

As they were all brought in, the Fallen Spawn fed on their dreams using the power of Mamon.

"[Corruption of Mamon: Dream Eater]!" The power of a voracious hunger devoured everything including dreams. All these dreams were being absorbed and the Fallen Spawn saw it all.

The memories of Krysta, Angelian, Monica, and Sherah all culminated in them falling to their knees as the Angel showed its real form.
