Return of Consciencea

A brand new Changeling has come to Equestria in the form of Pheromone. She is a unique kind of Changeling lost and forgotten to time capable of feeding on not just love, but also other emotions, and since magic is tied to emotions in Equestria, by feeding on enough magic, she can amplify her magic in any way. This new threat seeks to rule the Pure Changelings like she did before and almost takes over Destiny and Thorax's hives. They end up discovering from Mirage the Changeling that Pheromone is the last of the true Changelings, which existed before the Changeling Underground and was created by Princess Consciencea, but when Pheromone proved that this species was too dangerous, she had no choice but to regress them to feeding on only one emotion: love, driving them underground. (TBC...)

(Dr. Wolf's new TF2 Analysis episode TF2 Analysis: "A Change of Form" had me thinking about the concept of Changelings able to feed on more emotions. So this is the result.)
