Dan Vs. The Ruined Nation of Saddle Arabia · 2:03am Jan 10th, 2017
Shortly before Dan's departure to the Crystal Empire, he and Twilight and the others were informed of the attack on Saddle Arabia. The zebras, armed with weapons giving to them by Vice Grip, had launched an all-out assault on their smaller desert-dwelling neighbors. Because of their alliance with Equestria, Princess Celestia and Luna both departed with the majority of their royal guard to assist them in their hour of need.
That was the last time they were seen.
