Summary
After the Snap that never was, the Avengers and their allies awaken from a shared nightmare-visions of dust, silence, and loss that feel too real to dismiss. From across, they gather in midnight moments to unpack the grief of a war they didn't fight but still carry.
This is what didn't happened—but could have. A dream stitched from memory and fear, and the quiet healing that follows. No battles. No suits. Just truth, laughter, and the kind of presence that makes survival feel like a choice.
Midnight falls. The nightmares fade. And the stars bear witness.

Summary
Thousands of years ago, fairies ruled the earth. All that's left now are ruins from the old civilization--one of which is the Green Isle, an island off the coast of Ireland that only becomes visible once every seven years. It's during this seven year cycle when Cosmo, Timmy, and Wanda are invited on an expedition to the Green Isle by Cosmo's estranged father, celebrated Arfaeologist Professor Clary Pari Sattari. Cosmo wants to rebuild his relationship with his dad, but Wanda is skeptical. Does Clary have an ulterior motive, and does his expedition have anything to do with a fairy hacker whose activities are threatening the stability of the Big Wand?
