(The Spanish version will be published when the whole fanfic is done)
Equestria, The Changeling Lands, Zebrica, and many other kingdoms are at war
Yet the worst part hadn't come...
Machines were created to replace the hoofs on the ground, fueled by the power of love, but it's not as happy as it might sound. Love can only be extracted as energy by a very limited number of creatures, but ponies soon discover that love is useable through fresh blood.
The war went on and on. A machine was created to counter the last, and another was created to counter the last, an endless loop of death.
After the friendshipless days ended with silence, every creature focused on rebuilding.
But then came the Deep Tartarus discovery.
Now a single changeling machine, the last one to be made before the great harmony goes down into the Tartarus in the look for fresh blood.
The machine code...
