Heroes From An Old World

Heroes From An Old World is a Sonic/Kingdom Hearts crossover fanfiction which serves as the owned character's storylines of the Sonic Chronicles series which also includes the stories of Vanitas, Aqua, and the Lingering Sentiment. Any other inclusion of KH characters to this part of the story is unknown as of yet.

As this is the Kingdom Hearts Fanon Wiki, only chapters pertaining to Kingdom Hearts elements will be shown here.

Chapter 9: Assassin
The first hints of Kingdom Hearts is near the end of this chapter, where Gamble the Echinda and Furry the Fox land in a desert canyon due to a teleportation technique from Gamble, and the Lingering Sentiment arrives. The Lingering Sentiment stood up to attack, thinking Gamble and Furry were both parts of Xehanort, while Lily the Messenger watched from afar.

Chapter 10: The Twilight Project
The Lingering Sentiment continued to fight Gamble and Furry into this chapter as well. However, after Gamble delivered a sucessful Jack's Blade attack on the Lingering Sentiment, the Lingering Sentiment realized Gamble and Furry were NOT Xehanort, and he left the two quietly. Later on in the chapter, Gamble contacted The Scourge and told him about Xehanort and the Lingering Sentiment.

Chapter 11: Madness, Part One
The Scourge found an old tome at the near-beginning of the chapter which chronicled brief and half-accurate events of the total chronology of the Kingdom Hearts series, making The Scourge beleive there is a connection with Sonic, Sora, and the world he lives on, as well as the canyons themselves. However, since the tome didn't specifically say the Keyblade Graveyard was a canyon, The Scourge cannot make any conclusions yet. Scaith and Lily soon found the Vanitas Sentiment in the Keyblade Graveyard, with both making small eye contact and just staring at one another.

Chapter 12: Madness, Part Two
Scaith soon sees the Vanitas Sentiment try to attack him, but before he can land a blow, Scaith gives the Vanitas Sentiment his own being back, thereby making Vanitas reborn. The Lingering Sentiment soon arrives because of him sensing Vanitas, and Vanitas fights the Lingering Sentiment--believing it to be Terra--while Scaith and Lily watch. The only other mention of the KH series comes at the end when The Scourge plots to get the X-Blade for himself and open Kingdom Hearts for his own deeds.

Chapter 13: Madness, Part Three
Scaith and Lily comment on Vanitas and the Lingering Sentiment's fights at the beginning of the chapter, which is relatively short. At the very end of the chapter, Vanitas defeats the Lingering Sentiment and goes with Scaith to get the X-Blade back. However, the Lingering Sentiment says in a soliloquy that the Keybladers of Light would return to end this conflict. Future events would show Aqua being one of these Keybladers of Light.

Chapter 14: Gambling Fate
After Nicolette leaves the scene at Knothole Village unknown to the other Freedom Fighters, a small blue creature is staring at here. At the end of the chapter, the creature has been revealed to be a Flood Unversed created by Vanitas for the sole purpose of scouting Aleannas.

Chapter 15: Saving Nebula, Part One
An Unversed is seen spying on Warp, Scott, Theta, and the captive Gamble and Furry as they charge through the icy glaciers. The Unversed returns to Vanitas's side immediately afterwards, informing Vanitas through a telepathy link that there were people with negativity in their hearts within the icy glaciers. Vanitas offered to go out after them, which Scaith allowed.

Chapter 16: Saving Nebula, Part Two
Vanitas makes a minor role in this chapter, as he and some Unversed merely spy on Scott as he fights Scratch, Coconuts, and Grounder in their M6 machine.

Chapter 17: Saving Nebula, Part Three
Vanitas's first conflict with the protagonists is in this chapter, when he fights Scott and Aero in the glaicers alone. He manages to keep Scott at bay by tricking him and knocking him to the ground, making Aero transform into Darkspine Aero.

Chapter 18: Saving Nebula, Part Four
Vanitas managed to fight off Darkspine Aero, but he got bored of the fight and summoned a Trinity Armor to do him in while he ran off in a Corridor of Darkness with the injured Scott. He soon ended up in the Realm of Darkness, where he revealed to Scott about his plans to reclaim the X-Blade. He tried to kill Scott and turn him into an Unversed, but Aqua soon arrived and fought Vanitas. While Scott and Aqua fought off Vanitas, Darkspine Aero killed his Trinity Armor Unversed before falling unconscious due to overexerting his life force. Vanitas is soon beaten--thanks to Terra's and Ventus's Keyblades floating through the Realm of Darkness--but he flees and leaves the two for dead. Scaith is then seen performing something similar to Master Xehanort's extraction of Vanitas in Kingdom Hearts: Birth By Sleep as he summons Xaroe--Aero's Unversed--from Aero's unconscious body. Vanitas then managed to make a large crack in the glaciers, sending E-10,000 Ultranos, Warp, Nebula, Gamble, and Furry into a large icy cavern with no escape. Vanitas then floated down and challenged the five, easily dispatching Ultranos before the battle truly begun.

Chapter 19: Movement On All Fronts
Vanitas is shown attacking the group and easily fighting them all off, preventing escape by placing a barrier over their only exit. In the meantime, Aqua and Scott manage to escape from the Realm of Darkness thanks to the Tornadosword and the God of Dreams, and they arrive in time to knock Vanitas back and save Warp from death. Vanitas laughs and summons 1000 Unversed--comprised of Floods, Arch Ravens, Scrappers, Thorn Bites, Buckle Bruisers, and Wild Bruisers--before disappearing and ordering his Unversed to attack them. Aqua and the group fight some of the off, but they are saved by Nebula going into her Super transformation and killing them all off in a matter of seconds, before falling unconscious. In the meantime, Scaith introduces Xaroe to Vanitas and vice versa, while also informing Vanitas he must control his pride if he ever wants the X-Blade, or else Xaroe would get it instead.

Trivia

 * It was only recently INFERNOX changed the story's parameters to "crossover with Kingdom Hearts."
 * The ratings are actually on the borderline of "T" and "M."
 * Because the Keyblade Graveyard is part of Aleannas (and therefore Mobius) in this story, the Keyblade Wars may be related to Sonic the Hedgehog. However, this has gone unexplained as of yet, although the ties have been hinted to.
 * Chapter 19's original title was going to be "Unversed From Reality," as to reference it more to the 1000 Unversed battle. However, this was changed, as INFERNOX wanted to put movement in everyone's storylines, even though some storylines were not shown.
