Hogwarts: Alliance of Six Schools

[No system, Gou Daoliu. It fits the timeline of the original work and greatly expands the world view. Slow-paced bond development. ] There is more than just one school in the wizarding world: Hogwarts. Beauxbatons, Durmstrang, Ilvermorny, Wagadu, the Magic House... Each school has its greatest secrets, each school has its own magic, and its people who strive to move forward. At the end of the 20th century, the minions lurking in the shadows had reached out to the British Isles, tearing apart the already loose magical alliance... No magic school is immune to this. According to legend... At the end of the long night, what the Death Eater army saw under Hogwarts Castle was not just a mob... The rune horse knight spreads his wings across the sky, the sail battleship's cannon roars, the elite striker pulls the trigger, the druid priest sharpens his minions, the witch priestess holds her staff and prays... And the person who connects all the bonds in this wizarding world... The person who formed the largest wizard alliance in history... Only the one from Hogwarts who has mastered the art of turning yin back to yang and bringing back the dead... ... Soul ferryman.
