Just curious, but what're these things?
I've been doing a lot of T1 runs lately (building up Crowns to buy CE before I take on T2), and on some of the levels I've found something interesting:
I thought at first they were just found around Minerals or maybe at the lower depths, but then I found this at Depth 1 at another gate:
What exactly are they? I've only seen them a few times, and they look a lot like the patterns on the floor behind the Konjuring Kat, so are they related somehow? Is there something more going on in the game? Or are they nothing more than things tossed in there to make the levels look visually interesting?

Despite all their advances, gremlins have yet to master the art of drawing hopscotch squares.
And here I was thinking there was some grand conspiracy going on.
Thanks guys :).
Demonic Runes / Markings. Usually found on fiend levels. Just aesthetics afaik.
The Fifth Pentacle of Saturn combined with the meaning of the Seventh Pentacle of the Sun.
Two circles, denoting the angels names between the two. The center shows a resemblance to the Third Pentacle of Mercury. Although the angelic names are gibberish in this case.
Learn your occultism, people!
this discussion totally reminds me of this, which always gets a giggle out of me:
Ian WAS one of the art designers in this game. That may very well be the closest thing to an official explanation.
I find this amusing.
yeah....holy crap, have i actually been following his stuff for over 8 years? where does the time go?
