Queen Chrysalis, ruler of the changelings, is in trouble.
After the failed Canterlot attack, not only has she been forced to trade all the ponies she collected for the safe return of her subjects, but she is also about to be forced into signing treaties of peace that will leave her race crippled.

A strange creature is found trapped deep in the old hives, will it help the changelings rise again, or be the final nail in the coffin for the pride-blinded queen.

Sex tag for all of that juicy innuendo and passing references to sexual acts that any good changeling loves.
Takes place shortly after the wedding, no gak deer with wings here.
