*takes a swig*

Okay, here's the thing. What's your world like? What magic does it have? What kind of monsters and creatures are there?

Are there flying creatures? Then there's going to be a large amount of them underground. Are there siege units? Well, probably star forts. What kind of magic do they have to deal with ****? Like, are there storms out there which necessitate building into the sides of a mountain? Do they need to be built near a water source, or can they just conjure up water?
