Have you ever wondered how it was on the other side? The "evil" side? Athena, the daughter of Pitch Black knows. Shocker that he even has one. She lives with him underground in his hideout with his wife, Lynette and son, Isaac. They've all done a pretty good job of avoiding the Guardians. But, of course, Athena eventually meets the Guardians many times, but not in the ways you'd expect. She uncovers secrets about all the Guardians as well as their past life. She even finds a little surprising thing about her Dad, Pitch, and his past. Course being Pitch's daughter has its ups and downs, and everything comes with a price. When a mysterious half-sister (So Pitch had more kids....? >.<) enters Thea's life, everything turns even more twisted than before. Her bravery and skills will be put to the test as new enemies arise. (Edit 6/12/15: Wow I wrote this so long ago and it sounds really cheesy.)

After the epic adventure with Jack and the Spirits, here comes the story for the two daughters of the two first guardians of this world. Despite the contrast view of others about their relationship, they long to meet each other. Lumia, Pitch's long lost daughter, wants to find someone who can treat her well. While Jade, Manny's daughter, longs to befriend the discriminated daughter of the Boogeyman. Jade and her friends will lead the way for Lumia to learn what it is to live.
