I can’t remember the name or find it in any of my bookshelves, but I can remember that the aliens, in a show of force, nuke manehatten. From there Celestia goes (temporarily) evil, and pulls the ship out of the sky, leaving 5(?) survivors. From there a second ship comes, bombs the country side, then gets taken over by Luna.

Anyone know it?

I don't know why would you call Celestia evil for getting wrathful, though.

I say evil because she goes her version of nightmare moon, Daybreaker, and I couldn’t remember the name

I think i know the story, but i cant remember the name.

Is it possibly Into The Black?
