Urvén is the prime material plane within my 5E setting. It is a ring of continents and sea arranged on the outside surface of the petrified body of a Great Old One. Gameplay mostly takes place on the Riven Lands - the continents and islands that remain after a great calamity shattered the largest landmass several hundreds of years ago. It is a place of magic, regrowth and opportunity and is home to many different races, creatures and cultures.
