In the absence of the alicorns, the earth has fallen on times similar to those before the first Hearth's Warming, but with a different breed of Windigos. Dry winds and harsh temperatures scorch and scar the once beautiful lands, drying up even entire oceans. High in the clouds, the pegasi are disconnected from the strife of the other tribes, but still face their own issues. Rather than make civil arrangements and work out a trade for resources, they instead use their strength to impose rule over the earth dwellers. An all out war is coming, and lines will be drawn.

When Turncoat Magus decides he's on the wrong side and is cast out of the pegasus capital, he takes up arms with unlikely allies and vows to end the tyranny of his father, King Magus.
