Peak of the Middle Ages

Every September, there was a recruitment drive for military training. All the peasants, mostly men who were turning 18 or about to turn 18 that year, went to the military village, not far from the crusader camp, and were received. This was done by the captain of the knightly order of the crusaders, Jordan himself.
Toward evening, when almost all the arrivals were gone, a green-haired boy, who didn't even look like he was eighteen, entered the tent with the wooden desk where the reception was taking place. But he felt quite confident, and even chose the right tent, opening the dialogue with a kneel.
Good evening, captain.
A man with long black hair and red irises in his eyes, about 50 years old, looked at the boy with a puzzled expression, wanting to be indignant, but the boy got ahead of him.
I want to start training to join the army.

And how old are you?
The man asked with disdain and received a completely unexpected answer.
sixteen.
the guy answered, getting up from his knee.
No, no, no and no!
a stern voice of a man was heard, rubbing his forehead with his palm
Well, why?
At that very moment the krestyanen became indignant, after which he continued
Is it really so important to apply for education at eighteen?!

Your family still needs you because! God didn't give us life so that children could spill blood in the fields!
The boy was about to protest, but a man with long, purple hair braided into a ponytail and horns sticking out of his head suddenly walked in from the other side of the tent. He looked about 30, though he was actually 23.
What's happened?
A rough voice echoed through the tent. He glanced at the Vara, as if already guessing what was going on. His dragon-like eyes, with their yellow whites and sharp, black pupils, added an even more terrifying quality.
Peak, don't climb!
Said Captain Jordan, waving his hand towards the exit so that the man would leave, but he only approached Var, ignoring the captain's request so boldly.
What is your name?
The man above asked, approaching Varu with his hands behind his back and his posture straight.
