Petrov is smart and observant, folowing his intuition he warned his father about Roland while everyone else were sure of an easy victory.
Perov lived for several years in King's City, where he heard all kinds of rumors about Fourth prince Roland Wimbledon.

While taking glances from Aurelia, he is caught in a hot discussion about Roland's ultimatum. Nobles condemned the prince's actions as reckless and foolish and concluded that Duke Ryan have to do something about it. Rene Medde joined the conversation and boasted he would lead his family's forces.
After Petrov returned to the mansion, his father asked Petrov to send him a full report of domain population, revenues and production to prepare for war against Roland. When he tried to persuade him to stay in the rear and reminded him of unfulfilled predictions, his father angrily refuted him and reminded of ancestors' deeds.
A week after father's departure Petrov received a letter from Longsong Stronghold, written by Roland Wimbledon. The prince outlined duke's defeat and nobles' release conditions. Soon he arrived at the lord's castle and listened to unusual ransom details. Hearing that Roland would leave Longsong Stronghold in a few days he offered to manage the city on his behalf, which impressed the latter. Next day Petrov brought ransom list and signed an agency contract, after that he went to take away his father. When he found out that Jacques Medde refused to pay for his brother, he offered to ransom Rene. After return to the mansion, he told his father about Roland's conditions and his new status, on that Shalafi advised him to watch over the other great nobles and hire craftsmen from the North.
