With my D&D 5th edition game coming up fast, I've been toying around with setting ideas. I plan to be a little bit more bottom-up in my design than I usually am, if only because it seems that my last several attempts at starting a fantasy campaign have been false starts, leaving me with a lot of wasted time and effort.
I'm feeling a mashup of Arabia, Persia, various parts of northern Africa, and a little India. I'm looking mostly for flavor, rather than attempting to be historically accurate. (It is a fantasy game, after all) I'm thinking a mashup much like how the default D&D setting is a mashup of various European cultures.
I've spent this morning and yesterday reading Al-Qadim source books from good ol' 2nd edition. I was at first tempted to use Al-Qadim whole cloth, but I've since decided to take bits and pieces and generally use it as inspiration. I also plan to raid Spears of the Dawn (because I love me some Kevin Crawford)
Blast it, I'm already doing top-down. I think I'm going to back off and define one large city or perhaps fortress that will serve as a starting point for the campaign.
