Welcome, I'm somewhat new myself, but it took me longer to join the forum after I started reading the books.
As for my name, most of it is Elantris stuff (sorry) but mostly I just found it interesting that there are Aon's for lots of cosmere terms, and then there is one that means Unity. I decided that I liked that a term used in a large scene in Oathbringer also just happened to be an Aon, so I based my name on that Aon. I also liked the design of Aon Are, so that's an added bonus.
