Everypony who is anypony knows what happened at the near-disaster of the Royal Canterlot Wedding. The Changeling Queen Chrysalis captured the bride and impersonated her, invading the capital of Equestria with her swarm at her back, intent on feeding on the love of the loyal captain of the guard and capturing a swarm of ponies to feed her and her hive, wounding Celestia and nearly winning, before being ejected and tossed to her inevitable doom by an immense burst of love-fueled magic. The story is simple, it's straightforward, and it's obvious.
And, of course, incorrect in so many ways.
When you're dealing with Changelings, it is wise to not take anything at face value...
Two interwoven tales of the consequences of the Royal Canterlot Wedding.
Days after the wedding, Chrysalis is brought to trial by the Changelings for her actions, and sentenced to personality death without ever being permitted to defend herself, as the hive prepares for the inevitable war to come.
Months later, Spring Bounty is a mare on the run, fleeing from Changeling capture after being rescued by a pegasus named Papillon, determined to make an escape and seek protection and safety - if any such safety still exists.
