Well just made my first trip and found the sea dragon and after getting past it i found a room full of lava 3 precursor buildings and another sea dragon after barely getting past the second dragon i came to the very bottom with sand and these green cube clusters floating in the air looked a lot like the ion crystal any idea what these are and what their purpose might be?
