The year is 3053, the galaxy has been divided into 5 great houses in what is known as the Inner Sphere. These houses have been locked in an eternal struggle for dominance for thousands of years. All of that changed in the year 3050, when invaders from outside of known space began a push towards Terra from Galactic North.
However, in the southern regions of the galaxy, a small Periphery nation known as the Magistracy of Canopus, who's interests are far from galactic conquest, is under attack by the forces of House Liao. Leading their defense is a woman known to those outside of her close circle of friends as "Phoenix." who appeared in the middle of a battle some five years prior.
Titans of Steel and Honor is a MLP/Battletech crossover that's been on my mind for some time.
