Conquering the Duke
Ilian was not someone to use dirty methods to win a fight, he will always be a straightforward warrior. That was the way his Master taught him even if all his life had been a constant battle of wits and schemes against him. He was an outright person.
However, that didn't mean he was a fool and even if he was young, in fact, much younger than many of the dragons fighting in the tournament this year, he was a bit more experienced in fighting the ones hiding in the shadows. Secret attacks, assassination attacks, poison, concealed weapons, potions, and so on. Not only once he was attacked by those. He had been protecting his mother for so long too.
