A real treat of world and campaign building wealth, this guide makes building easy, and it's Handy for Solos, too; it's very deep, but you can just roll as you go, or roll ahead and set up a very detailed world: even if you struggle with creativity. Even if you like making your own world(s), it's still useful at filling in gaps to plug into your concept(s) and fill in the bits you might not like creating: worlds (or galaxies) for your campaigns or campaigns for your worlds. Many useful tables, and concepts, and factions, and... well, you get the idea. Oh, and art, great art. Thanks Yochai Gal, another great resource! Time to go fill some more cairns.
