Prologue:

Once upon a time, long, long ago -like more than fifty years ago- a baby was born and a God planned to overthrow his brother, but was destined to be defeated by this baby, his own nephew. To prevent his downfall, the God sent his minions to dispose of the threat, but unbeknownst to him, they didn't succeed as he thought. Time skip about eighteen years and a series of 'heroic' events blah blah, the baby -now a young man- defeated his uncle, got the girl, and saved the day, blah.

Left to pull himself out of the main river of the Underworld, the God was bitter at his loss. He had never wanted to rule the Underworld, he just had gotten the leftovers while his brothers ruled the Skies and the Seas; while the rest of the Gods resided Olympus, he was left to dwell in darkness. His Wife, who could only spend half of the year with him at a time, wasn't even here to admonish his actions, as she was with her mother for a few more months.

As time passed and the daily work carried on, the God could admit that he might have acted rashly in his plot, and that the Titans were not a convenient method of conquering; While they were more muscle than mind at that moment, who knows what they would have done if they broke out of that single-minded rage. By the time his Wife joined his side once again in the underworld, the God was ready to put the failed plot behind. He was Hades, Lord of the Underworld and while his brothers still ruled the Skies and the Seas, his kingdom is where everyone eventually ended up.

Sadly while the Lord of the Underworld seemed to make peace with his failure, his brother Zeus, the Lord of the Skies and King of the Gods, did not. He was still furious with his older brother even years later and thought that his brother needed to face punishment for his actions; It didn't help that his son Hercules -who had since married the girl he saved and started a family of his own- had his adventure spread and retold, eventually becoming more exaggerated and construed than before.

While the God considered what to do about his brother, a formally Beastly King was in a summit with his royal council, announcing his proclamation for nationwide 'peace' in the form of confining every villain and their followers within the realm to a barren isle. As the council murmured of their various past experiences with the villains, the King, Adam, went further on to explain that not only would he be collecting the ones currently running around, but would also have the ones that were dead brought back to life; while this announcement brought mixed reactions, many of them had agreed that death was too lenient for their villains. When the Council meeting concluded Hercules, who was a part of said council, asked to talk with King Adam about how his 'villain' -being a God- would be trapped on the isle. As the King was about to reply, the Fairy Godmother urgently strode into the room and quickly recounted to King Adam -and by association Hercules- that when she was planning out the requests he had assigned her to do for the isle, a deity announcing himself as Thanatos the God of Death, appeared in her office.

The God had informed her that even her own magic could not bring back the magnitude of people they had planned to do, and that even if she was able he would not allow it. The Fairy Godmother went on to explain that the God had informed her that if they wanted to continue this they would have to get the express permission from either of Thanatos' superiors, Hades or Zeus. The Fairy Godmother ended her explanation bringing to light that even if they were able to bring back the villains and have them on the isle, even her strongest Magicks would not be able to stably confine all of them AND strip them of their powers indefinitely. After a moment of tense silence, Hercules notified the two that he could convene with his father and see if he could agree to order Thanatos to revive their villains, and possibly provide a way to confine them with their powers stripped.

If you haven't figured it out yet, when Hercules went to Zeus about the King's plan and the Fairy Godmother's predicament, the God was more than happy to oblige. Zeus thought that it was a fitting punishment for his brother, and a compromise instead of sentencing him to Tartarus for a period of time. To further help them contain the various villains and God, Zeus commanded Hecate and Hephaestus to assist the Fairy Godmother with her task. The last thing that Zeus mentioned to his son was that the King would be required to have Hades' work sent to him on the isle, in part so that he would not consider it a vacation from his duties as Lord of the Underworld, but also prevent a power vacuum from forming with Hades gone.

Hecate and Hephaestus established a barrier around the Isle that stripped beings that entered of magic and access to their powers; the only way to exit the barrier would be to use one of the devices that Hephaestus manufactured to create precise holes on its surface. Soon after completing the preparations, King Adam was able to see his proclamation go to fruition; within months and various manhunts, every person considered a villain or their followers were confined to the Isle.

Not long after the villains were confined to the Isle was that Persephone, Hades' wife and Queen of the Underworld, decided to join her husband without being prompted; While some wondered why anyone would willingly trap themselves on an isle on an isle full of villains, the King and his council were fine with it. It became an issue the following spring when the Goddess Demeter appeared before the King during a council meeting demanding that her daughter be freed. After a long parley between Demeter, King Adam and Persephone, they agreed to continue the longstanding arrangement of Persephone staying with Hades six months of the year and the other with her Mother.

Even missing her daughter for six months would be too much for Demeter, as she thought that Hades being out of the Underworld and trapped would nullify the original arrangement. After convincing Zeus that the terms of the original arrangement were void, he ordered that Persephone be removed from the Isle as it was only Hades' punishment and not hers. Demeter in her self-interests hadn't realized that in doing so she had damaged her relationship with her daughter in one of the worst ways possible, by forcing her away from her child.

Now, you may be thinking 'that's sad but what does this have to do with anything?' well, that child that Demeter forced her to leave behind because of Auradon's stupid rules is me; My name is Korie, daughter of Hades and Persephone, and this is my story.

Author's Note

Hello everyone, and thank you for choosing to come see what I've written! This is my first published fanfiction that I've written, though I have planned and started multiple other ones across different fandoms. This story out of all of them was able to be published first because inspiration just hit me like a train and I had to write it down. I've been inspired by the various other Descendants fanfiction and I wanted to take a crack at it in my own way. Hopefully, I will be going through all three Descendants Movies, but at some point, events will definitely go full AU.

As the story unfolds you'll see that I'm mixing in some general Greek Mythology, as well as pieces of plot from the 'Isle of the Lost' book series; The thing is I haven't read the series personally so it may only be points of the plot that were on wikis and reviews and not the detailed book scenes.

In case you were wondering, I know that the movie Hercules takes place in Ancient Greece, and Descendants has modern-day technology. But since Descendants in itself merges all of the stories together you can suspend the accuracy of historic periods. I set the events of Hercules (starting from the beginning, the birth of Hercules) about 52 years prior to Ben's Coronation, meaning that the time between the end of Hercules and the creation of the Isle was 14 years.

For face claims of various characters, I'll put who's who before the author's note of the chapter they're first mentioned in. For Descendants characters that are in the movies, they're the same.
