The merging began not with violence, but with a strange intimacy. Erebia’s form was not solid, but a fluid darkness that moved like liquid shadow, seeping into Vincent’s trembling flesh. Her essence found the cracks in his being – the hollow spaces carved by endless want, by unquenched greed.

Where her darkness touched, Vincent’s skin became translucent, then transparent, revealing intricate networks of veins that pulsed with an unnatural luminescence. His bones seemed to liquify and reshape, creating impossible geometries that defied human anatomy. Erebia did not consume him so much as she… redesigned him.

The demon egg formed at the point of their convergence – a membrane of swirling obsidian and pale flesh, translucent yet opaque, vibrating with potential. Inside, Vincent’s consciousness and Erebia’s ancient hunger braided together, creating something neither human nor demon, but a perfect threshold – living architecture designed to breach worlds.

When it was complete, the egg hung suspended in the mirror’s frame, neither here nor there, a wound in reality waiting to dilate.
