Telvurin

During the Age of Legend, the land encompassing much of the River Kingdoms was a type of hunting reserve for the elves of Kyonin known as Telvurin or the "Shifting Lands". For thousands of years after the elves' exit to Sovyrian just before Earthfall, humans moved in to explore the area, often running afoul of the indigenous lizardfolk, grippli, and fey.
