[City of Avalon]
The pitch of the shriek was so high, that6 it literally affected everyone who heard its cries. Because of its high pitch shriek, people were forced to cover their ears, as they endured the pain ringing in their ears from hearing the deafening sound of the living ice bird. Some of the people who weren't able to cover their ears on time, were now wringing in pain in the ground, as their ears bled and their hearings destroyed.
Of course such wound could be easily healed with the use of magic and alchemy, but the pain that the person would have to endure was so much that it could somehow traumatize them from all objects or things that produce high pitch sound.
