This story is a sequel to A New Friend
It has been more than a month since the events in the changeling hive took place in the last story, "A New Friend". Chrysalis, now left without her changing ability and magic, has gathered her changeling swarm with the help of her daughter, Princess Naractia. Now she plans to get revenge on the ponies that caused her to lose her power.
However, Naractia hears her plans and flees to Ponyville to warn everypony about Chrysalis. But once she leaves the hive, Queen Chrysalis sends a group of changelings to kill her daughter. Now the only one who can help Naractia is Rowan, a unicorn from a different world, student to Princess Luna, and wielder of the Element of Courage.
