What goes in a Swamp? I am currently making a campaign that has three areas.  One of the first area being a swamp.  I have thought to flesh it out as best I can, but it still feels empty.  So far I have put a couple camps nearby, a hamlet for some information on how to get out of the Swamp, a couple tribes, and a giant tar pit that is used to dispose of things.  Despite having all of these things, the swamp still feels empty and I want to have a couple sessions in the swamp before moving to the next area.
