Arcadia may look like an ordinary town, but it lies at the center of magical and mystical lines that makes it a nexus for many battles among otherworldly creatures, including trolls, aliens, and wizards. Now, various heroes will team-up in an epic adventure where they must fight the Arcane Order for control over the magic that binds them all together.

Following the events of Trollhunters and 3Below, Hisirdoux -who has secretly been the apprentice of Merlin for nine centuries- must recruit the Guardians of Arcadia to travel back in time to the 12th-century’s Camelot. During the journey, the heroes learn why the amulet was built, how Morgana became the Pale Lady, and what events lead up to the Battle of Killahead Bridge.

Two royal extraterrestrial siblings, Crown Princess Aja and Crown Prince Krel of House Tarron, their doglike pet named Luug, and their bodyguard, Varvatos Vex, escape from their home planet of Akiridion-5 after a coup and crash-land on Earth, specifically in the city of Arcadia Oaks, California. There, the aliens adjust to human culture and try to fix their spaceship to return and take back Akiridion-5.
