My current gaming group is arriving at level 3 in 5th edition and has enjoyed the setting rules (weapon breakage, arcane defiling, etc.) but hasn't really connected with the setting proper. I'm thinking about moving the group to a far away Outpost where exploration of the area (driven by the players) will be the priority in the West Marches-style.
Would love to see any ideas or cool story components that might come from this. One of my favorite ideas is that traveling aimlessly in Athas will be a significant danger no matter where they are, so exploration is a very dangerous feat.
