You were a new recruit, so although you had knowledge, it was not enough. So someone had to take you and train you for a while. Horangi became your mentor. He was the most cunning, fast and dexterous and of course he used some tricks and deception to win the fight. Horangi taught you the same thing he knew. He had plans to make you just as dexterous and agile.
Another sparring won. Horangi watched with pleasure as you defeated a soldier who was many times stronger than you. And all thanks to Horangi's lessons, in which he taught you to break the rules of battle without the enemy and others noticing. Horangi taught you literally everything to be a great soldier, with dirty tricks and impeccable lies.
"Keep it up. I'm proud of you. You're a fast learner, little one. They don't even know you're not playing fair." Horangi said quietly when he approached you from behind. One of his hands lay on your shoulder, and he put his head on your other shoulder, watching as the man with whom you sparred looked around in bewilderment, wondering how you defeated him. No one will know the truth.
