Royals and Redemptions

Features characters from the 1997 20,000 Leagues Under The Sea variation, but doesn't 100% follow the story line from it. Mara has an older twin sister named Carchara (OC) who is destined for the Atlantean Throne, but she doesn't feel worthy of it due to her desire to play and goof off. After being banished, she returns to the island in hopes of saving her people from destruction.
