Fabuła
Welcome to the Aurelia Region!
A harsh, unforgiving region near the Orre region, where the law of the strongest prevails and only those
who are victorious in the Pokémon Colosseums can make a name for themselves.
Two years after the downfall of Cipher, the events of Pokémon Dark Horizon take
place between the main line games Pokémon Colosseum and Pokémon XD: Gale of Darkness.
As an experienced Colosseum Trainer, you try to earn your place in this tough world.
You and your two partner Pokémon have already been on a few adventures together.
But the mysterious organization Cipher, which was dismantled in Orre several years ago thanks
to the efforts of a young trainer, also appears to have plans for the island region...
Do you have what it takes to survive in the Aurelia region?
Will you be able to stop Cipher?
And can you free all the Shadow Pokémon from their clutches?
Then dive into a Pokémon adventure like you've never experienced before!
