the ring of writing on the inner circle looks like a random hodgepodge of alchemical symbols and symbols derived from the zodiac. gold shows up three times, glass, beeswax, burned alum, water, "aqua regia", arsenic, lime... it's a long list that makes no sense. it doesn't really take much to guess these probably have different meaning to this cult but without more examples of the order's useage i can't tell you much about what they might translate to in the halo of the sun.

in the outer ring, the four large symbols are also pretty mishmashed. the top seems to be either the evil eye or the eye of providence. the bottom symbol looks a bit like a wave and a trident but on closer inspection seems to be from a document supposedly written by a priest named ubrain grandier. it was a supposed pact with the devil and was used in trail against him before he was executed after being accused of bewitching people. here is the document. the symbol on the left in the outer ring is obviously some scales, symbolism unknown, and the object to the right is completely unidentifiable. if i stare at it long enough it looks like a key.

gonna post the runes the next comment because holy crap is that a lot of talking.
