When c!Andy goes to check on Gruce, they find c!Ethan doing the same. In typical c!Ethan fashion, they go on an adventure after they talk. While exploring some ruins, they find some weird scroll c!Ethan can't understand.
C!Ethan takes the scroll with him. As c!Andy is around that scroll, though, their arms start to burn more often.
How unfortunate, for the Universe's angel, that this magic is not well studied?

Fun little crossover fic that I'm cross-posting on Ao3. Chapter format will be a little different depending on where you read it; if you want less, but longer, chapters continue reading here, but I will be posting longer/"combined" chapters on Ao3. As I get done with chapter sections (such as character POVs) they will be posted here, but they should still end pretty okay instead of a random break. I'm not great at dialog though, so they might not act like in canon
Little side thing: This is for fun. I'm not going to adhere to what "could actually happen", it is fanfiction. HOWEVER, I am going to be adding personal theories/headcanons. If you notice me having written something down as fact when it hasn't been confirmed, don't tell me.
