Byrus

“Its appearance was so numbingly horrific that she, unlike Whitney, was unable to scream; she tried, but her voice failed her. The darkness and rain mercifully concealed many details of the mutant form, but she had an impression of a massive and misshapen head, jaws that resembled a cross between those of a wolf and a crocodile, and an abundance of deadly teeth. Shirtless and shoeless, clad only in jeans, it was a few inches taller than Eric had been, and its spine curved up into hunched and deformed shoulders. There was an immense expanse of breastbone that looked as if it might be covered with horns or spines of some sort, and with rounded knobby excrescences. Long and strangely jointed arms hung almost to its knees. The hands were surely just like the hands of demons who, in the fiery depths of hell, cracked open human souls and ate the meat of them.”
