The bottom third of Champion's Isle is France, with the small coastal and rural town called Villenueve. There is a PokéCenter, a small library, a bakery, and a tavern. You can find a Cleanse Tag and the Round TM. Talk to the townspeople, and one fisherman will give you his Super Rod. The rest of the villagers speak of a beautiful girl who wastes her days with her nose in a book. In the middle of town by a fountain, a burly man and a woman in blue are having words.
"Be mine, Belle," he says. "Make me the happiest man alive and become my wife."
"I will never marry you," she says, attempting to storm off.
The man in red grabs her arm. A familiar dark aura flares around him. "But we would be so happy! We'd have plenty of kids."
"Gaston, no means no."
You intervene, and Gaston is surprised at your appearance. "Don't you dare get in the middle of this. You can't keep her away from me. We were meant to be!"
Grunt Gaston sends out the Psychic/Fairy humanoid Mr. Mime. His move-set of Mimic, Psybeam, Encore and Toxic is super frustrating, but you take it down. Next is a Psychic Wobboffet, who has a reflexive move-set and the trapping Ability Shadow Tag. If you carefully avoid it Destiny Bond, you won't take too much damage to your team. Next is the pure Fighting Machamp. Watch out for his Poison Jab and Thunder Punch! Gaston made sure his Fighter had good coverage. You pound him into a pulp, and he's down to his last Pokémon, the Fire/Dark tiger Incineroar. He winks at you, showing off his muscles, and his Trainer does the same.
"He's really rare," Gaston gloats. "Won it in a bet in a far off region."
Incineroar snarls, coming at you with all he's got. His move-set has great coverage with Flamethrower, Darkest Lariat, Low Sweep and Bulldoze. He gives you a hell of a time, but you eventually defeat him.
"But... But we're both beautiful," he laments, handing over your prize money. "Just because you've stopped me this time doesn't mean I won't be back. I always get what I want."
Grunt Gaston runs off, dropping the Swagger TM.
Belle approaches you. "I want to thank you for saving me. It's not much..." She pulls from her basket a Moomoo Milk. "I have to get back to my father, but thank you!"
You can follow her down a country path, where you can be jumped by Mr. Mime, Floette, the Normal poodle Furfrou, the Fairy perfume bird Spritzee, and the Steel/Psychic mirror Bronzor. You reach Belle's house, and you watch her feed the chickens. Suddenly, a Mudsdale appears.
"Phillipe! What are you doing here? Where is Papa?" The horse whinnies wildly. "Take me to him!" She hops on his back, and they disappear into the nearby woods.
If you check around before you follow her, you can find a Magnet on the table next to one of her father's inventions inside the house. In the chicken coop, you can find a Lucky Egg.
Then you can follow her into the woods. You soon come to a fork in the road. One path leads to the City where Belle's father was heading to a convention. However, the hoofprints in the dirt lead you in the opposite direction through the forest. Sporadically, you'll be jumped by Mightyena, Vulpix, the Electric/Fairy mouse Dedenne, the Normal/Flying bird Swablu, the Bug/Flying Vivillion, the Grass/Poison Roselia, and the Psychic humanoid Gothorita. Look closely and you can find an Antidote, a Paralyze Heal, and the X-Scissor and Energy Ball TMs. Cut down a couple small trees, and you'll find an Ultra Ball and the Thunderbolt TM.
Finally, you come upon a large Gothic castle. At the gate, you run into a stout man who is out of breath. He sees you and huffs, "He has my daughter!"
Inventor Maurice sends out the Steel/Psychic bell Bronzong, Bronzor's evolution. It has Levitate, which eliminates its Ground weakness. You defeat it, and he sends in Dedenne. This unique type combination means it's only weak to two Types: Ground and Poison. You take it down, and he's left with the Steel/Psychic Metang. He just learned Meteor Mash, which will hit even harder with its STAB. Ultimately, you are victorious. "Please, save my daughter," he begs, then runs off.
You enter the gate, pass a garden, and ascend the staircase to the front door. An old woman in an emerald green cloak stands in your way. "Do not interfere."
The Enchantress sends out Gothitelle, Gothorita's evolution. She has the move-set Shadow Ball, Dark Pulse, Feint Attack and Psychic. You faint it, and she sends out the Psychic/Fairy Gardevoir. Its Ability Trace will copy its opponent's Ability. You take it down, and the Enchantress is left with Roselia. It knows Toxic, Poison Jab, Giga Drain and Petal Blizzard. You cut it to pieces and win the match! She steps aside so you may enter.
You look around at the elegant foyer, ornate, yet dusty and haunted. You call out, but it seems to be abandoned. Before you can get too far, the ground beneath your feet begins to shake. You wait for the tremor to pass, then look around. You can find a Choice Specs and the Endure TM lying around. You ascend the staircase, and it splits. Another quake breaks loose parts of the ceiling, and it comes crumbling down. When the dust is settled, you see that the right staircase is blocked off by the rubble, so you turn left.
A large beast appears, roaring. "No one is allowed in the West Wing!" He sends out Ursaring, which you've dealt with before. You use your normal strategy, but something is off about the Ursaring. The Type effectiveness is different, but you don't understand why. It's not until you attack it directly that you realize it's not an Ursaring at all – it's the Dark fox Zoroark! Before you can finish it off, the Beast switches into the real Ursaring. You defeat it, and he sends out Mightyena. You beat the wolf, and he sends Zoroark back out. Now that the Illusion is broken, you have no problem taking it out. The Beast roars in anguish, causing the castle to tremble even more.
You continue up the stairs to a dark room. Belle seems to shine in her yellow gown as she stands next to a glowing red rose. Surprised at your sudden approach, she sends out Dedenne. It gets powerful STAB on Charge Beam and Play Rough. Once you have that mouse scurrying back into its Pokéball, she sends out the Steel/Fairy key ring Klefki. Its Prankster Ability gives its Status moves priority. You destroy it, and Belle sends out the Ghost/Fire Litwick evolution, Lampent. This one has the Ability Flash Fire, which boosts his Fire type moves if you use one on it. You snuff it out, and she sends in Bronzor. Its Ability Heatproof will cut your Fire Attacks, but of course you take it down. Next, Belle sends out Roselia. Before you can faint it, she calls it back, where it's healed by its Natural Cure Ability. Belle replaces Roselia with her signature, Gardevoir. It's the highest level you've faced yet, equipped with a powerful move-set of Psychic, Magical Leaf, Dazzling Gleam, and Future Sight. Ultimately, you win!
"That was wonderful!" She hands you the Hyper Beam TM and one of the fallen rose petals. "Here, we don't have much time." Another tremor ripples through the castle, and you hear crumbling in the distance. "Quick! I'll only be safe here a little while longer. The rest of the Isle has been overrun with Villains. Give your Treasures to the Guard at the entrance to Victory Pass and get rid of the evil they threaten to spread. You're our only hope." She heals your team and wishes you good luck.
The exact thing you feared has happened: the Isle has fallen into darkness. You must return to the woods to the fork in the road and head towards the city. You see a tall cathedral in the distance, towering above the other buildings in Paris, and it's bathed in that dark aura you've been seeing so much lately. You better hurry!
