Descendants- a retelling

Twenty-nine years ago, all the kingdoms of the earth got together and waged war against their enemies, banishing their greatest adversaries to an island, surrounded by a barrier that mutes all magic. Most of the kingdoms joined together to become the United Continent.
Since the Great War, peace and harmony has lasted. But the new generation is stepping in. When the prince invites four descendants of the island to come and live in the United Continent, the children of the greatest villains get a chance to prove that they aren't defined by their parents, and show that the children of the heroes, aren't always the good guys.
