The Lands of Alterra
The climate, flora, fauna, and terrain vary widely all across Alterra. There are high mountainous regions, deep seas, thick foreboding forests/jungles, frozen wastes, rolling plains and deserts of sand and scrub. Also, there are deep cave systems below the planets surface where all but the bravest of heroes would be unwise to travel in.
Alterra has been in a recovery period over the last millennia.
