Ethan sure wished he had kept reading more about the spell's description before casting it. He just thought it sounded cool to use magic to travel back in time; he never expected to have his soul travel back and not his physical form. He ended up possessing this woman in the past, which was weird, but it got worse. Luckily, the book was ancient and existed even now, but according to the pages he was stuck. It was a one-time-only spell. He wouldn't have minded being this woman for a while, but forever? Ugh.
