A Courtyard!
Six months passed since Jacob broke the first shackle, and he had started waiting for a distraction, but there we simply no movement in the vicinity of the castle.
He was also running out of ration, and he could only go on like this for two more months.
So, today, Jacob decided to move out and hunt for Extraordinary Dark Beings!
Because the time spent in his room wasn't gone in vain, as he had already made progress with fluid acceleration and had even more profound control over his heart rate and breathing.
Jacob knew the clash with extraordinary dark beings was inevitable, even if someone distracted the Lich King and his ministers. So, he was preparing for his next move. Even if no distractions come, he knows he doesn't have the luxury of time to wait until it does.
Since no one was coming, he had to move out himself.
