I can't seem to find the fey merchant - I'm hearing that they should show up on the property list, but I see no such option, and as far as I can tell I need them in order to buy a steel casing and progress.
If none of that made sense, I'm trying to construct the bomb. I can't find the steel casing. I've finished every other main girl's questline, and can't progress the church or the fey questlines until I construct the bomb.
