"They brought us food, they brought us peace, they came with the ocean breeze. They gave us a tongue, they gave us a home. From the Aegaean is where they come" ~ first two verses of an ancient gryphonian poem

Two worlds. Two worlds, once close, closed, then forgotten. Equestria is on the verge of defeat and Earth is close to what would become a new world war. In desperate times full of harm, two worlds run into each others arms

Note: This story doesn't represent any of my political beliefs. I changed the worlds a lot. I changed the course of earth-history as plausible as possible for me and Equestria is far less advanced (!) and has a much bigger (!) population than in the show, as well as much more cities and territories. The sun and moon work just as they do on earth and so on.

Have I mentioned that I'm not a native English-speaker?
