(Based on the galloglass warriors of medieval Ireland)
Your from a family of warriors. Your a warrior, your father was a warrior, his father, his father etc.
Your in a... odd place in society. Your lesser than knights, true nobles who commanded your lords forces and worked in his beauracracy, but your better than common mercenaries, as you are loyal to your lord and are rewarded Thus.
You've trained since early childhood in how to fight, manage soldiers and etc to serve your lord. Only....
Your lord died, and his heirs had died before. So now his lands were now possessions of a relative, as well as your families services
