Story: While on a visit to her family at the Palace of Eternos, Adora senses something wrong back in the Whispering Woods. After dinner she transforms into She-Ra for a swift journey back to the camp teleporting right to Whispering woods, via The Crystal Castle and using Swift Wind to fly there. And Adora's intuition was right! Queen Angella was on her way to meet Catra who had asked to join The Great Rebellion. Glimmer finds a note at The Laughing Swan Inn, were Bow and Kowl were sitting at a table. Glimmer tells Bow, "I never trust Catra. We must follow Mother to see nothing happens to her." Adora, Madame Razz, and Broom join them in the trip to The Black Wood onboard a flying clipper ship. They land and enter the Black Woods with Madame Razz riding Broom right into a tree. They had gone only a few miles when a ferocious Mud Monster blocks their way. Quickly, Madame Razz works a spell- but instead of chanting, "Monster, Monster, change into air," she says, "Monster, Monster, change into a bear." The bear charges the group, but Adora holds out her hand, stoping Bow from shooting and arrow, and the bear gently takes her hand. "I knew he meant no harm," said Adora. Around the next bend in the path, they meet Catra. To frighten the search party, Catra transforms to her cat form and stuns Glimmer with her magic. Bow catches Glimmer, while Adora sneaks off and changes to She-Ra and to counter Catra's magic by changing her sword into a glittering mirror. She holds up the mirror to Catra and says, "Come see what a beautiful creature you are. Why, you could be queen of The Black Wood." To see herself better, Catra removes her magic mask but without the power of the mask she disappears, magically teleported by the Sword of Protection. Then the rescuers find Queen Angella tied to a nearby tree. Bow says," She-Ra's power to trick Catra saves us all once again." The story ends with Glimmer and her mother embracing in joy.
