Crossing the Floating Lights: Harry Potter

The Green Snake falls into Britain and, having lost her memories, enters Hogwarts. The White Snake settles in Paris, moving among Grindelwald’s followers. As Eastern and Western magic collide, the sisters find themselves on opposing sides amid the turmoil of 1926. An ancient demon cultivator faces off against Western spells, while secrets and betrayals pass back and forth through paper cranes. At last, on a battlefield where their blood pact is shattered, they will rediscover each other’s true names.

Note: This story has a mountain of original worldbuilding. It’s my first long work, so it will have plenty of bugs. Criticism and corrections are welcome. If you don’t think you can handle that, please don’t open it.
