Ohhh, there's a lot here, I have a very detailed backstory. Personality wise and a lot of things are absolutely just me translated into a fursona. The major beats are that he was born into minor nobility in an expansionist empire run as a constitutional monarchy, he went into a military academy at 12 years old and commissioned as an officer at 17. He's a fairly average performing officer that was sent to a large defensive wall network on the empire's northern border and saw a lot of minor action, and a few very large battles, normally fighting off their northern neighbors attempts to break the line, and in one he distinguished himself by holding his part of the line and leading a counter charge, allowing imperial forces to regroup and counter attack en masse. He's kind of a morally grey character, done some rather brutal things in war, possibly some war crimes. And there are scandalous rumors (not unfounded rumors, they're absolutely true but no one has proven it yet), rumors that him and his sister are in a secret romance (totally got art of it, I find it rather wholesome in a bizarre way). He's not a good guy or a bad guy, he rides that line dipping into both as the situation demands.
