Any initial thoughts on the ring and what it may symbolise?

I feel it is a ring worn by a certain group, probably Knights of Malta,
indicating membership such as a masonic ring worn by masons.
It's meaning is unclear to me at this point.

The ring was known as a palindrome, the words can be read the same in every direction. The meaning: The farmer Arepo works wheels. Makes no sense but the full meaning of the words has been a matter of debate for centuries. It once served as the personal mark of Constantine the Great.

No idea. But the Sator thing is both fun (as in trying to work out its meaning - something that apparently still has scholars guessing) and clever.

I agree with you John >2 JohnDBurke:
Seeing has scholars struggled with interpreting it all these years, not sure it’s something we’ll solve.

Either worn by the Knights of Malta or some sort of secret subset of the Knights.

Used now as a symbol of the inner group of the order. it holds the key to Constantine’s treasure —or ‘gift’, whatever that may be. The Nostra Trinita?

I hope it will turn out to.symbolize something good rather than bad.

My guess it's an outward sign of the Knights of Malta when they were among non-Order peoples. Sort of a "Hi, My Name is" but with more Knightly emphasis. The palindrome was fun, and I tried to figure it out. No luck!
