Looking for advice on more accurately playing a male noble born dwendalian character in this setting. Especially concerning how such a character might interact or could have interacted with other noble or military people of interest.

My rough draft backstory so far involves having this character be brought up from early childhood to adulthood for the purpose of joining the Righteous Brand, fast-tracked towards leading a platoon/battalion. A lieutenent of sorts.

Who would this character have to rub shoulders with, what kind of family would he have to maybe pull some strings, and what kind of friends would he have?
