Yakushi Kabuto at Hogwarts

This is a world touched by the Conjunction of the Spheres from the Wizard universe (HP).

It has legendary artifacts far surpassing the Deathly Hallows.

From time to time, a special world sends it unusual creatures.

It holds memories of a legacy lost for a hundred years.

Now, creatures from several other worlds are about to arrive.

Perhaps a white-scaled, eight-headed serpent will battle a giant ancient magical war statue; perhaps a white-haired professor in name only will speed up the progress of potions; or perhaps a figure capable of overturning the Wizarding World will rise to prominence.

Perhaps a broken soul will be torn apart, someone will be stripped of their sense of self, or a person with a damaged mind will spread a vile potion.

It is a complex world, and a world full of miracles.

Worlds involved: Wizard (some lore and characters), God of War (related stories and artifacts), Pirates of the Caribbean, Harry Potter (main world and timeline) (the legacy), Naruto (special characters, including Kabuto, and knowledge of chakra), parallel transcendent worlds (strange souls)

P.S. The world-travel stories will only take place in the Harry Potter universe. After a short opening section in which the Wizard universe explains Kabuto’s arrival, it won’t appear again. There will be no plot set within the Wizard universe.

[The opening blends elements of the Wizard universe’s Conjunction of the Spheres, Kabuto receiving Orochimaru’s blood during the Naruto era, and some notable lore from the Harry Potter universe concerning Nicolas Flamel. See the related works for reference.]

The final boss is not Voldemort, though Voldemort himself is more powerful.
