I am going to be running a 5th Edition campaign set in a future of a previous campaign. I want to add "magi-tech", but very sparingly.
My question is: Are there any official sources for this type of thing? Rules or anything? I know 5E is new so it might not, but I thought I'd ask.
I've heard that Eberron has some magi-tech things (I've never played it). Would the campaign guide for 4E be good to pull ideas from or would it not make sense rules-wise?
