I found the second piece of the Trismegistus! (no spoilers)

Okay, either I am missing a spell upgrade, or otherwise I must be completely blind. I've looked at all the earth elemental area, as well as all of the main area and the fire elemental area, all in their light perspectives. No orb in sight. Please tell me something, is the orb behind the big pillar with the hex at the bottom in the earth elemental area (light perspective)? If so, this means I will need Upheaval III if it exists. If not, I'm thoroughly stumped.

I just hope that its not hidden inside an already-opened treasure chest, that would be plain cold-hearted. =]
