Let me start by saying im not entirely sure if this is where I should post this.
Been dming for about 2 years and currently running a pathfinder campaign. Im wanting to use the brp system for my next campaign but im not sure where to start. It is a homebrew.
Setting: In short were on a "desert" planet very dry very sandy lots of western themes here. There will be alot of Coal powered things almost a steampunky vibe. Airships will be a thing or something close to them probably blimps. Low tech guns like revolvers, lever action rifles etc. Now where its going to get a little complicated probably is I want to throw in a very small amount of magic. I thinking in the form of gems that can power scifi like weapons and vehicles. Rifles that can have fire or lightning effects, or faster ships. maybe power cities or have the ability to create water and such.
Just looking for some resources to use here. Anything would help.
