DO NOT get overly concerned about Mary Sue status. I have seen people, myself included, twist themselves into pieces over this. The RPC has a deeply ingrained obsession with no one being too terribly special or interesting - and theres nothing wrong with it - but you can go too far with it as well. Do not forget the RPC is by no means a large, or majority population for Balmung. What is said here can not be assumed to just apply to the server at large, not even close. Don't worry about fitting in here nearly as much as writing up shit you and your rp partners enjoy.
Don't be afraid to go off the beaten path, don't be afraid to ignore lore either if it makes for way more interesting RP. This games lore is objectively bad, and sometimes tossing it do to your own thing or do bend something makes things so much more enjoyable. You learn by doing, so go ahead and start rping and make your mistakes. I make mistakes everyday, even an hour ago I did with a writing project I'm working on with Ottos IC wives. Learn by doing.
