The problem is that the shields worked as solid shields as well as mufflers so knocking the bells loose wasn't going to be easy. The first bell creeper went down from the sweep but rolled away to come to his feet again. The second was a woman who flat out hissed out of frustration for her bell not working. Time to drop some of the pretenses then.
She and the third bell creeper opened their mouths and began to shriek. After a few moments the shrieking took on a strange sort of medley, a carol to be specific. O Come All Ye Faithful to be exact.
Molly felt the power thrumming out from the chorus and cursed under her breath. That was a summons. They were going to have company. She dropped the veil on herself and one of the shields around the bells popped free. "Faith! They're calling in the rest of the Salvation Army!"
The woman whose bell had come free began to clang it in earnest now that it was free sending sonic peels against them.
