Assëässe
Assëässe is a medieval fantastic world that exists in a theorical sliver closest to the intersection of all the famous Dungeons & Dragons worlds across the planes of existence. It is an adventure-rich world where Player Characters actions really matter and have an actual impact on the world.
Beware, as the world is self-balancing, there are such things as too-much of good or to much evil in the world. Not every action has an immediate consequence to it, but everything counts in the balance. Maybe the gods are watching, maybe not, but rest assured the world has a tendency to fix itself...
