Ulysses gritted his teeth because of the sudden assault and the failed plan they had. He looked around and saw that all of the sentinels were down because of the ear-piercing sound that the shadow was creating. He was forced down to his knees at the effect of the sound waves that dominated the room.
Ezio, who understood the plan, started to create a gate but because of the high-pitch sound from the shadow that suddenly enveloped the whole hall, he lost his focus and also covered his ears. Compared to them the others were not doing well because some of them started to bleed from their eyes, nose and ears.
It was not looking good for them. All of them were down and that's the only time that the screaming stopped. They were relieved that it stopped but another problem arose, any attack against them right now would be fatal. All of their men for combat were on the ground and suffering the after effects of the high-pitched scream.
