Lost Lands
Welcome to Heathwell, a small town in a lost western continent.
You are one of the very few, foolhardy, people of this world who call themselves an adventurer. Beyond the walls of this meager town - built by and for people like you - is a dangerous wilderness unmapped and unexplored. Those who dwell in this outpost call it certain death past the edges of the enormous magic circle that protect the town. It is a land of lost legends, old magic, and of course untamed wilderness. Whatever ravaged the world thousands of years ago ended any civilization that may have dwelt here.
You come by magic circle and you are here until you retire. Occasionally supplies may be sent from the mainland via this circle, but they are rare. Whatever you find you keep. Maybe you can strike up a deal with a kingdom to gift them any lands you may clear? The world is your oyster. And yours alone.
