Hello all! I'm a new player going through my first campaign and eventually I'd like to DM my own game after getting a bit more experience. The general idea is that it's a world that's mostly islands after the Aboleth's flooded most of the surface in a bid to drown the ilithids and enslave most of the mortal species. I'm hoping to use some of the aquatic monsters, races, and such, that aren't usually played out on land. This is a long way off since I'm hoping to do a few more games as a player before I try my hand at DMing but I wanted to know if there's a good place to discuss campaign setting information here or on another site, and if any other folks that make up their own campaign settings have any tips.
