A third idea could be a story where a young wizard from Hogwarts discovers an ancient connection to the world of Eragon. They accidentally stumble upon a portal that leads to Alagaësia. There, they befriend Eragon and learn about a different kind of magic. This could lead to the wizard bringing some of the knowledge of dragon riding and Alagaësian magic back to Hogwarts, changing the way magic is taught and understood there.
One idea could be a magical exchange program. Wizards from Hogwarts and Dragon Riders from Alagaësia meet and learn from each other's magical systems. Harry Potter characters could be fascinated by the bond between Eragon and his dragon Saphira, while Eragon might be intrigued by the variety of magic at Hogwarts like Transfiguration and Potions.
Maybe a dark force threatens both worlds. Voldemort somehow discovers the power in Alagaësia and tries to use it for his own evil purposes. Eragon and Harry team up, along with their friends, to fight against this new threat. The wizards use their spells and the dragon riders use their combat skills and dragon powers to combat this common enemy.
