Ancasta, Goddess of Rivers and Rains, invented for After The End, a personal project RPG set in post-Roman Britain.
Locals worship Ancasta to bring healthy water and plentiful rain to the land. She can sometimes be seen walking in rainstorms and tending rivers in secluded areas, where water spills from her amphora and she cleans the streams with her staff of river reeds.
Also, village leader designs which govern small settlements across the land.
