Story description;
 
Ten years have passed since the fall of Queen Luna and her husband Dust, and Equestria has been forever changed thanks to the death of the rulers and the events that followed. There is no government, no laws. No morality. The concept of family and friends no longer exist, taking loyalty and love with it. The only thing that governs the land now is the icy winds and deep snow; the longest and coldest winter in living memory has struck the land, and is holding it in its tight grip. Famine and hate brews as the cities and towns fall one by one. The people have no hope left, and only care about surviving another day, no matter the cost.  
Pulled from his home into a dying world, the human Anton struggles to survive together with his new and unusual friends. As the fiend known only as Thanatos tears through Equestria like a whirlwind of hatred, Anton’s search for the truth about his dead brother takes him to the Crystal Empire.  
A shadow is falling, all hope slowly fails and the ponies of Equestria have said their last goodbyes. It falls upon Anton and his friends to fight for what little is left of the world.  
War is on the horizon, the enemy nameless but not forgotten.
