Entropic Knell
From Warhammer 40k - Lexicanum
The Entropic Knell is a great bell that was forged in Nurgle's realm, and to hear its grim tolling upon the winds is a death sentence. For its sound, heralds the arrival of the of Nurgle's Plague Legions and such is the Entropic Knell's power that a single peal reverberates for long minutes, spreading dread and despair even over the clangour of battle.[1]
