The Harsh Isles

Centuries ago, a landmass called Yaven existed. It wasn't that large, but large enough to be have a significant level of differing environments. Rainforests, mountain ranges, deserts, tundra, and grasslands all existed on this landmass. Along with this diverse landscape came a healthy and diverse population of living creatures with varying degrees of development. Inexplicitly, the landmass was shattered some centuries ago, breaking Yaven into islands that each has its own unique population and landscape. The civilizations here are scattered and hard, bringing these lands to be called the Harsh Isles.
