Glad you have been enjoying the game!
At the very top right of the map, pass the yellow fields there is a green mountain with trees. Big floating rings that glow blue, the north east boss is under that. There are black basalt rocks that bridge all the islands. if you go to the southern middle smaller island and then head north you will get to the main second portion of the biome across two bridges.
Working on adding more animations and content each update!
