Summary
A bunch of ideas for crossovers that I have but can't write, so if anyone wants to they can use these.
Note
I've been working on a crossover fic with Nico going to Hogwarts for about a year and a half now but I've never really had the motivation to really continue with it and school keeps getting in the way. I've got about two chapters finished so it's not gonna be completed any time soon but if I actually finish that I might do some of these ideas. It probably won't happen so if I lose hope I might post that idea on here.
