Dullions are a cruder form of their cousin the golem and are also capable of releasing great strength. They can be made of hay, tar, or other similar matter and they do not have their own free will and only to be instructed by its master. The only known ones is in the hands of the Society of the Evening Star and of the Somber Knight. In the series it was said that there was a warlock that knows the extinct art of making dullions. Note that their creation is an art.
A Dullion interupted Kendra and Seth from escaping Errol Fisk with the help of Vanessa when they knew Errol was part of the Society of the Evening Star. The dullion was made of hay and straw and was said to have been also armed with hard matter underneath its weak outer covering of hay. To Seth who had not yet drank milk by that time it looked like a moving heap of hay and also looked stupid to him. The dullion crushed the roof of Vanessa's car before they escaped the Society and Errol Fisk.
Another dullion is owned by the Somber Knight that lives in the catacombs of Terrabelle. The creature is bull-shaped and made out of tar. It rode to battle against Celebrant and his guard togheter with the Somber Knight in Wrath of the Dragon King. The bull lost most of its back parts.
