Lands of Mystery
The world is ancient in two ways:
1) The setting is closer to the “ancient world” than medieval europe. Chariots, slave galleys, plumed helmets, bronze and iron, etc. I’m not using any specific time period or place, so expect a wide range of technology and cultures across the world.
2) The world is very old and many civilizations have come and gone before the current age. The ruins of Isprea are still around to explore. Remnants Bael Turath and Arkhosia may be found. Legends hint of even older empires with strange races and forgotten gods.
