Screaming Bells are holy altars from which the Grey Seers preach to the the Skaven. The Bell is an ever-present symbol in the legends describing the creation of the Skaven race, and its sound reaches deep inside the evil hearts of the rat-men, inspiring awe and devotion. In battle the ominous sound of the Bell can be beard above the clamour of the flghting, a message of death for the rat-men's enemies and of victory for the Skaven.
