Confluence Where the Four Elemental Planes Collide

Confluence is small for a world. It is a scrap of contested space where the four elemental planes meet. It is just a triangle at the tip of a spur of the Elemental Plane of Earth, bounded by Fire, Air and Water. There is no sun, the light of Fire and Air provide just enough illumination.   At it's edges, new land is repeatedly created and destroyed, the intense magical environment often producing short-lived tribes of inhabitants or monsters out of nothing.   Some of these denizens have the intelligence (or luck) to push inland, away from areas where they risk re-absorption into the primeval chaos.   The centre of Confluence is (slightly) more stable, and has become a refuge and home for waifs and strays from across the Multiverse. They have built a town there, calling it Sharrow's Hold, after it's founder and leader. Sharrow holds no formal title, but all at the Hold respect him. The consequences of crossing him are rumoured to be... interesting.   Sharrow's Hold acts as a trading post and waypoint for travellers from across the Multiverse, and all are welcome no matter their species or beliefs, as long as they behave reasonably well while in town.   Also.... this world is fresh and new, and very much a work in progress !
