As soon as Rex jumped outside through the window, the first reaction of the 3 Priests in Black was not to go after him but to observe the sacred altar.
They constantly heaved sighs of relief as they scanned one place after the other, this was until they saw the library as their eyes started burning in rage.
Due to some unknown reason, the thief did not take any of the sacred books or pamphlets but the mere fact that the library was ransacked and that the sacred books were scattered was enough to send them into the highest level of anger.
"Damn thief!!!"
All 3 of them roared in unison as they turned before storming out of the altar room like a group of enraged bulls who were out for blood.
Thud!
As soon as Rex landed on the floor after escaping out of the altar room through the window, he rapidly scanned his surroundings, this was when he discovered that every escape path that he previously marked was already blocked.
