If you are a rogue, perhaps you started developing your abilities around 7-8-9 years old throughout your teenagers years, stealing food at the marketplace
. You might also have followed or force to follow a street gang. Knives are easy to hide and carry while you are running away.
If you are a fighter, perhaps you have followed a role model during your teenagers time and practice with the sword (GoT Aria practicing with the sword her brother gave her). Although I would see Aria as rogue/fighter. What you think ?
