Ok, so I don’t think I’m gonna do a story, just prob some drawings here and there. Long story short(ish), Harmony stumbles upon a secret portal to the Zebra village. She is welcomed, and asked to forge an alliance between ponies and zebras. They send their king to Ponyville, but he is terribly wounded (his horn breaks and his wings are practically torn off) by rogues in the forest, who will do anything to stop the ponies and zebras from getting along. Eventually, the royalty teams up to defeat the rogues and open the gateway between the zebras and the ponies.
 
This picture takes place while the rogues attack for the first time. Harmony just kind of froze, which she will regret pretty much forever. Immediately after this whole thing, she trains to become a guard, which she now is.
