Short and young, wielding a big sword
A short young man, Nathanial is only 25, being the youngest of three sons of the previous emperor. He was the most militaristic of all the sons. He stands at 5’6" he wears nice clothes, but practical. Seemingly always ready for a fight
During his time in the military as a commander then general he led his army through a series of victories against the greenskin tribes and beastmen brayheards. Through military cunning and tactics he proved superior to his other peers in leadership.
But when it came to leading the people outside the military, he was harsh to the civilians, pushing them hard and devoting everything to the military. Perhaps it was to eventually overthrow the previous heir who had passed, but at this point it’s up in the air
