Harry and Leon arrived in a mirror dimension that appeared as a white space with a black tree in the center. A dark skinned knight with short black hair approached them.
"Greetings." The knight said. "My name is Saint Washington, guardian of the Western Multiverse."
"Western Multiverse?" Harry and Leon gasped. "What's that?"
"The Western Multiverse is a collection of worlds that originate from the western hemisphere of the globe, more specifically America, Canada and England." Washington explained. "Some of these worlds include Star Wars, Marvel, DC, as well as your world, the Wizarding World."
"Why are you telling us this?" Harry asked.
"The Western Multiverse has merged with the Eastern Multiverse, guarded by my friend, St. Hanako." Washington explained. "An 8000 year old evil Egyptian witch known as Hatshe has merged the multiverses together, creating a multiversal paradox. If you do not convince Hatshe to separate the multiverses, both multiverses will be destroyed."
"How can I convince her?" Harry asked.
"You need to go to Egypt to find the green water that will be used for the antidote." St. Washington had said. He sent Harry and Leon to Egypt, right where a pool of the green water was, inside the tomb of Hatshe.
"Leon, get a bottle, a chalice, any container you can find." Harry told Leon. Leon found a glass bottle with a cork. He took a sample of the green water in the bottle.
"St. Washington tells us to get the green water for the antidote, but doesn't tell us the other ingredients." Leon ran into a stone tablet with Katy Perry from her Dark Horse music video on it.
"Harry, look at this cool stone tablet!" Leon said.
"Leon, we aren't here to sightsee." Harry told Leon. Harry saw a stone tablet that had the green water, a scorpion, and some purple herbs on it.
"The green water…a scorpion…purple herbs." Harry thought to himself. "Maybe these are the ingredients for the antidote!" There was a cauldron sitting near an ancient tomb. A scorpion came biting at Leon, but he killed it and threw it in the cauldron.
"Great, now we need the herbs." Harry said. There was a rumble in the tomb. The coffins started to open and out from them came hordes of mummies with spears.
"They are onto us!" Harry shouted. The purple herbs were in a garden area that was crawling with mummies.
"LUMOS!" Leon announced, casting the Lumos spell. The mummies were blinded and stopped attacking Leon.
"This'll work, thanks!" Leon said, taking the herbs. Leon placed the herbs in the cauldron as well as the green water. He combined the ingredients to make the antidote. Hatshe was released from her tomb. Hatshe was a powerful pale white skinned woman with red eyes, black hair, and a black robe with golden accents.
"Who dares disturb my slumber?" Hatshe questioned.
"We did!" Leon said.
"You have awakened me for 8,000 years at long last!" Hatshe said. "Prepare to…DIE!" Hatshe started shooting lasers from her eyes. Harry used the Sectum Sempra curse to counter.
"Now Leon, the antidote!" Harry told Leon. Leon threw the antidote to Hatshe, splashing it on her body. It began to sink in as she stopped attacking Harry.
"Right now, I apologize for merging the multiverses together, and now I will separate the multiverses once and for all." Hatshe said. She separated the multiverses, creating an effect that caused the alchemical nations to separate from the Wizarding world, and form into their own planet. Gina was sent back to Hogwarts, stuck in the Ravenclaw dormitory.
"I am going to miss Roy Mustang." Gina said, going to sleep.
Back in Amestris, three different Edwards arrived in Resembool. The Manga Ed, the 2003 Ed, and the Brotherhood Ed were all in front of Automail Rockwell.
"Who are you people?" Brotherhood Ed asked.
"I am Edward." 2003 Edward answered.
"I am Edward too." Manga Edward answered.
"Well, if there is two more of me, then that means we can work together to beat this Lightning fellow wherever he nests." Edward said.
"LET'S GO!" The Eds said in unison. They went inside Automail Rockbell so Winry could give an explanation.
