Okay, So I had a new idea of a crossover, which came to me after watching A Choice With No Regrets and reading Harry Potter (again). Anyway, the idea was, what if Harry and his sister (since I love adding an oc for some reason, sorry if that bothers people) are hit with a stray spell or sentenced to the veil and instead of dying are sent to the AoT universe. Only, they get separated. Ivy, my oc, wakes up in Underground City with her brother nowhere to be found, even with the aid of magic. Sometime later, she meets Levi and Farlan and gets close to them. The story continues from there.
