Demigods go to Hogwarts

When Hecate feels that something isn't right in her pet world, she sends thirteen demigods to look for what's wrong in the wizarding world and to make an alliance with her people for the future. The seven, Reyna, Thalia, Calypso, Clarisse, Nico and Will will have to trade their swords for wands when they get transported to Hogwarts.

Hi everybody, I'm really really bad at descriptions sorry. The story takes place after the giant's war and the war against Voldemort.
This is my first fanfiction (actually my first story on Wattpadd) so please don't write too many mean comments, I'm a newbie.
Disclaimer:
The characters all belong to J.K. Rowling and Rick Riordan, I don't own them. The only thing that is mine is the plot. Plus, I don't think I going to add OCs. (Pretty sure that's how we call characters invented by the author or something) This counts for the whole book because I don't want to add a disclaimer at every chapters. So yeah, that's all. :)
⚠⚠ Just for info, I update randomly so sometimes I can write like three chapters in a night or something and sometimes I just forget even though that would not happen very often ⚠⚠
