One thousand years ago, in the wake of the banning of the pegasi clans and in the dawning horror of the Maresidian burning, Man were brought to the land of equestria by the artifacts of their creators, the First Civilization. There, the mares Shadow Kicker and Sunbeam Sparkle befriended the human stallions Amal Bashir, an Assassin, and Jacob, his brother, a Templar Knight. Through this alliance, man had helped rebuild the broken empire, and with their pony comrades, man sought to build a better republic. These are their stories.
