Sylvester's plans didn't end with killing the Crown Prince, however. Killing the man was just the beginning, a means to an end. More than that, what he wanted was to lure the second prince, the genius in runes automation, to his side. He could imagine how much the man would impact the world by incorporating runes in Sylvester's ideas for various machines.
He had seen the spark between the Emperor and the second prince, Jinn. The Prince wanted nothing to do with battles, fighting, or politics and was sort of a researcher. So, Sylvester decided to throw the bait.
On a usual outing with the Princess, through the use of subconscious manipulation, Sylvester made Fernis ask her second brother to join along. So, with him as a guard, he escorted them to the palace gardens, where the two were to sit, talk, and eat.
