This character is inspired by Eveline from Resident Evil 7: Biohazard as well as some homebrew worldbuilding I started last campaign.
Eva is a 10-ish-year-old human girl with no memory of who she was before she woke up surrounded by ripped-apart corpses. Looking around, she found a document with her picture, calling her a “Target,” likely meaning she was kidnapped, and that was how she lost her memories. It still didn’t explain the dead bodies, but she had to leave. Grabbing what she could, Eva set out into the frozen Icewind Dale.
