If you figure out what to do with this 4 "Essence of" items please send me a pm! Maybe its not in the aplha Version but maybe it had do do something with this 2 burial mouths and the levers there. I split my party so I see that the lever in one side have effect in the other side. Maybe I have do to something with the essences there?
If you know the general method with the lever puzzle then you might still be mixing up Air and Water. The symbols aren't very clear. One looks like either a puddle of Water or a cloud (Air) and the other could also be interpreted as meaning either Air or Water. I got them the wrong way round initially. It all worked fine once I had them right. I haven't found a particular use for the essences.
