I found the exploration point (240 to Kiseev Crag, 300 to Sokota Island, 410 to Leical Falls), however, there was no way to interact with it. Is there some associated quest I need to trigger first?
I originally auto-pathed to the Shakatu Abandoned Pier, then I auto-pathed to this lake close to it. You should be able to just walk right up to it, I didn't have to search for it.
