Kinwarest
In the vast forests of Kinwarest, where the tops of trees are not even visible from the ground, hides a marvelous treasure in the center, miles upon miles into the luscious, dense, green forest, only interrupted by large clearings every so often, filled with bustling cities and markets, pathways leading practically anywhere, Trading Hubs dotted around the dirt roads and busy taverns placed carefully around the edges of the clearings. Some, go on for miles. Others, perhaps a kilometer, but they are all trapped in the same place, the infinite woods of the great Kinwarest!
My original ideas and inspiration for this world come partially from the D&D campaign that I'm running with some friends, but also from the Star Wars moon of Endor. It is also inspired by several real-world Forests and Rainforests, such as the Amazon, the Daintree Forest, and the Monteverde Cloud Forest Reserve.
