In the world of Destiny, a terrifying Taken invasion occurred at The Guardian Tower on Earth, wiping out The Guardian Legacy and the Human, Awoken and Exo race.. All that's left is one lone Warlock who survived the invasion and flees to the planet of Equus and lands in Equestria. There, he makes friends with the residents of Ponyville, including The Mane 6, The Cutie Mark Crusaders and evens finds love with one of The Ponyville Day Spa ponies. (I'll leave it to your imagination of which one it is.)
On the run from the galaxy's most feared enemy and a traitor to The Legacy who was once his ally, our Guardian protects Equestria from Queen Chrysalis and her Changeling Army and Tirek, but all the while prepares himself for the day his old friend finds him and destroys the galaxy's last hero and one and only protector once and for all.
