What sort of person would just...create worlds like ours?
I can see where it might be useful. I'm still...trying to understand technology here. We don't have it in my world.
Pure iron, salt...those are things that I'm familiar with. What makes water holy compared to regular water? I'd like to learn more about your demons, Sam. I need something to keep busy.
I don't know if I could re-invent them. Armin probably could though, if he were here. He is another friend, a genius, really. I do have mine with me. If you know of someone who is good at mechanics, they could probably rebuild them.
We generally wear them at all times and luckily, I was wearing mine when that device pulled me here.
