After a mission, Pearl and Garnet found an artifact like a cube, which teleports Steven and the gang to a new world. First they thought they were traveled back in time until they found something gems don't remember existed on Earth. Dragons!

Everything's going according to plan. The screaming death's back with her mother and Berk is saved. But then she comes down to have a word. Ammolite is left aghast and Toothless is left drooling.

Many of you may know the tales of the Crystal Gems. However, Earth was not the only planet the Gems colonized. Far from Earth exists a planet known as the Barbaric Archipelago. It, too, was once a place of interest to the Homeworld before they were driven away. Unlike Earth, though, it was not a rebel band of Gems that sent them running, but the planet itself.

We are the Dragon Gems/We'll always save the day/And if you think we can't/We'll always find a way (Music based on the extended Steven Universe theme)
