stuck as saint

so its my first saint playthrough and I am enjoying it so far(I love swinging around with the grappling tongue). But I am not sure what I am supposed to do next. I went and met pebbles, then I went to moon, Both didn't say much to me or gave any directions. I am at the second highest karma level right now. I went and saw all the echoes( that I know of) but the pilgrimage passage shows that there is one missing. I went to the ones in Sky Islands, chimney canopy, the under hang, shoreline (on top of moon's structure), farm arrays, and subterranean, in that order. While I was in Sub, I saw all the void fish swimming down and thought I might as well follow, AND I FOUND A GIANT PIT where the depths should have been. I tried falling down but just got teleported back up, so don't know what's that about. I went to moon again to see if she does have something to say, but she basically just said heya and no instructions. I feel a little lost. Where do I go?
