Narnia outside Hogwarts

Narnia:

One day, the mother of the children named Peter, Susan, Edmund, and Lucy Pevensie sent them to another family. In the new family, they found a wardrobe that led to Narnia. There, Edmund "befriended" the Snow Queen, but they defeated her. They also met the Lion Salon and became the guardians of Narnia. Well, that's a short summary. Oh, and Peter is 16, Susan is 15, Edmund is 13, and Lucy is 12.

At Hogwarts, depending on the main character, Harry was in his 3rd year. Harry had friends Ron, Hermione, Fred, George, Ginny, and Nevel. Slytherins Draco, Blaine, Theo, and Penny weren't friends with the golden trio; they were enemies. Only in this chronicle, Black is already free and communicates with Harry, and Buckbeak wasn't executed. Harry, Hermione, Ron, and Nevel are 13, the twins are 15, and Ginny is 12. The Slytherins are all 13.

One day, the Chronicles, who were returning to Aslan's castle, encountered a portal... it was a time portal, and they were sucked into it... They found themselves in the Hogwarts courtyard, where there were a bunch of children from different faculties and years... The portal closed behind them, and all eyes fell on them...

I just can't think of or write anything else anymore...you are Peter, Susan, Edmund, or Lucy, your choice, but you will be hanging out with the Gryffindors, and the Slytherins will be bothering you.
