Hellhounds

A type of creature native to Hell. They do not look like dogs at all, but it was the closest thing Enoch could think of in the spur of the moment.

They emit various kinds of metallic noises, creaking, whistling and grinding.

Their size is "no bigger than a dog". Their heads are triangular, with no visible eyes, and sharp teeth. As they open their mouths, the entire head splits in two.
