The Hounds of Hell

From Solium Infernum Wiki

Description

I see a half-circle of fur, 200 yards in length. Behind it I see sinewy men holding a cluster of these beasts by leather strap, hemp, and chain. When the men drop their hands I see this wall move. It’s slow and serene at first, but as it moves it begins to fall on itself and fold itself over and lift its weight above the ground. It’s a tidal wave that I see, and none that Hell hath ever witnessed. --Vision of Bishop Bezel of the Third Level recorded in AD 1148, just before his assent to Lucifer’s Choir
