Alliance -- A KOTLC Descendants AU

For as long as the Neutral Territories have existed, the land it inhabits has been called the Isle of the Lost by it's residents. Home to the infamous rebel groups, the Black Swan and Neverseen, it's a place in shambles and ruins. There is little order, and what is there is enforced with violence, melders and fists and knives. On the other side of an ocean are the Lost Cities. It's home to the infamous Eternalia kingdom, where Elvin royals are sent to learn at the prestigious academy of Foxfire, all shining crystal and glistening crowns and delicate objects.
When they're brought to Eternalia on a Royal invitation, Sophie, Keefe, Marella and Dex Dizznee come on a mission -- break down the barrier by the end of their first trimester at Foxfire. They're welcomed by Prince Fitz, son of Della. the Beast, soon to be King of Eternalia. Their worlds can't be more different -- there's an entirely different balance in each, and as it is, the entirety of their world is about to know it.
