The most common variety of demon in existence, a demonic beast is just as its name implies. It’s pretty much the demon version of a wild animal. With limited intelligence, it’s not known for plotting or deception. They tend to attach themselves to characteristics of certain animals, especially vermin, and then take up residence in dark, private places, often times only revealed by a persistent presence of pests and the disembodied, hair-raising sounds of its growls if one ventures too close to its hiding place.
These beasts are fairly harmless if left alone, and can often be expelled fairly easily if needed, but they have been known to become extremely territorial and violent. They shouldn’t be taken lightly under any circumstances.
