An AU of the Hearths Warming Eve Story
Four centuries ago, the advanced civilizations of mankind fell to the horrors of hatred and warfare; the holiday of Unity Day reminds them of what they've lost as they struggle to rebuild. Humanity passed through its trial-by-fire, and has finally set aside pointless conflict; not all are as lucky, however.
A recon unit, called to investigate wendigo sightings on the borders of human lands, encounters three lost ponies whose nations are embroiled in a bitter war of annihilation against one another as an endless winter ravages their homeland. Though reluctant to become involved, one human ranger will try to teach them the harsh lessons humanity has learned – before they suffer the same fate as the old world.
