Horned Ones are also known as Horned Rats. They are the daemons of the Horned One worshipped by the ratmen / skaven. Each horned one is a tall, lithe, humanoid creature with the head of a rat, and two sets of horns (one usually long & slender, and the other curled around the back of the ears like rams horns). Strong and imbued with diseases, poisons, and magic, they make for powerful opponents. Many carry a great sword dripping with diseased venom, and to the ratmen, they drive these mortals to acts of atrocities against all other life.
