In a reality that Humanity has always existed on the same planet as Ponies and all the other creatures who inhabit that planet, this story follows Centurion Lucius Vor. The Roman Empire has expanded her reaches and sends her Legions to break all those who disagrees. Equestria being one Nation that prefers peace over all was just another nation on Rome's list. That was until the fatefully day of the VII Legion: Invictus fall from power along with many other Legions.

Lucius, even war stricken, tries to find the clear path but is only forced to bring memories back to light by a persistent Mare. Dark forces move against an entire Planet and threatens everything that all the Native species hold dear.
