Fair warning, I'm going to start rewriting this story soon, so I wouldn't suggest investing too much time or effort into it. I'll post a link to that story once I start writing it. Honestly this story is rather poorly written (it was my first completed story, to be fair), so it will definitely be worth waiting for the rewrite. It's gonna have a new plotline, new scenes, new characters; the whole nine yards.
A young colt named Sundance is cruelly stolen from his home by the military while the rest of his town is slaughtered, and is raised with many other foals to fight in the Clan Civil War. Upon reaching twelve years of age he is moved to the Sibko with the other freeborn cadets from his home town where they train to become MechWarriors. However; things are changing in Clan Draconequus, and these young soldiers will soon see the worst ponykind has to offer.
Meanwhile, tension is brewing in Equestria, hundreds of light years away. Discord’s anger at the loss of his friend to the Clan Invasion has reached its breaking point, but his weakening powers leave him unable to seek out the revenge he desires. Fueled by half a century of boiling hatred and a stinging betrayal, Discord will stop at nothing to sate his now twisted thirst for justice.
