So, I've been wondering about the shrine itself for a while, though what actually intrigues me most (currently) is the art below the statue. It's unique to this piece, I've not seen it anywhere else in the world... so I was wondering if anyone knew (or could find out) what's up with the serpents below.
There's a large version of that image. You'll notice also that it's not just merely a mirrored texture which would be the easy thing to do. I've looked up serpent lore and things related to gems/crystals or whatever it is they've got a grip on... and come up with nothing.
