I’ve my theory because i want so hard a no-mafia character for Italy <.<
That symbol remind me a robot (one eye) with something that seem horns. Leonora Botruvio has 1 eye and has a good expanded mask.
She is an artist, but we can also assume that she is a restorer -> Archeology.
We have also a Art Gallery in Rialto, the Payload goes from there to Talon Castle, where we have a Hera statue.
So, she could be on work to restore cultural heritage, keeping in touch with all over the people that can guarantee her to reach her objective.
Another thing: in Petra we have a winged lion, that is the symbol of San Marco in Venice.
Just my mind that flows anyway.
Here a good thread about Leonora info: https://us.forums.blizzard.com/en/overwatch/t/please-tell-me-leonora-botruvio/78174/22?u=otamega-2461
Edit: I’ve noticed now that if we see better the Leonora’s image, it seems she has synthesizers behind her head that come in front of and it could seem that “horns” of the symbol on Petra
