In the middle of the night, Princess Cadence and her husband are woken by the news that a Changeling drone has been captured. The creature is alone and unaggressive, showing no wish to attack or change shape. Its fate is decided without much difficulty--as an obvious reject of the Swarm and a threat to Cadence's people, it must be destroyed.
But this is no ordinary drone. It can speak, and appears to be separate from the hive mind of the Swarm. It claims to have been sent as an ambassador--Chrysalis, queen of the Changelings, wants to forge an alliance with Cadence's kingdom.
But why now? Why send this strangely intelligent drone? And how will Cadence's people react to learning that their rulers are harboring a Changeling?

WARNING: Contains an OC, much headcanon speculation, and possibly violence/gore further in.

Spartans never die, they're just missing in action. This has never been more true for Jorge-052 as, after activating the slipspace drive that was supposed to kill him, he is instead flung into a strange world where war is but a distant memory. Will the aging soldier be able to adapt to this new peaceful planet? Or will his only salvation be found in finding a way back to his own chaotic universe?

A single changeling is blamed for making Chrysalis' plan to take over Equestria fail. He's banished and thrown out of the hive, ending up somewhere far away.

Luckily, he ends up not too far from a certain well-known village, where he can feed to his heart's content.

Needless to say, not everything goes according to plan.
