Avro wants to go to university to see the big city and meet new ponies. The only problem is, war breaks out between griffons and ponies, and as an eighteen-year-old, he has no choice but to join up. Before he does, he meets a beautiful mare named Mossy Landscape, but has no chance with her.
Joining the Royal Pegasus Force, Avro goes to war, dropping ordnance on griffon cities in the face of overwhelming danger. But what will become of him in the most dangerous theatre of war, and what will become of his love for Mossy Landscape?

This is based loosely (very loosely) on the European Bombing Campaign during WWII, told from the side of the Allies. As such, some of the themes can be quite sad or upsetting.
