Thorax has just been named the king of a new hive of changelings that have turned on their queen. He is now tasked with reforming the rest of the "black" changelings in his hive. It hasn't been easy and three changelings in particular have given him trouble: his brother Pharynx; Ocellus's best friend Elytra; and the former general of Chrysalis's army Scutellum. Pharynx is wild but seems to still have a desire to stick with the hive. Scutellum, on the other hoof, is violent and fanatical and has influenced Elytra to remain loyal to her "mother". Can Thorax and the other reformed changelings convince them to turn on their evil ways, or will Scutellum threaten an uprising and ruin all of Thorax's hard work?
This story takes place between the events of episodes "Three's a Crowd" and "To Change a Changeling" and sets up for events in my series Flurry Heart's Story.
