This is an article on the deity Ydersius. For information on the ancient serpenfolk empire of the same name see Ydersius (empire).

The ancient demigod Ydersius (pronounced yeh-DER-see-us)[1] is the patron of the serpentfolk, a race of snake-men who battled the forces of ancient Azlant in the time before the Age of Darkness. He was driven underground during these wars and forced to hide in the Darklands realm of Sekamina. In one of the final battles of the Azlant-serpentfolk war, Ydersius became known as the Headless King when he was decapitated by Savith, a mighty Azlanti champion. Still believed to be living in two pieces, his mindless body is said to thrash in the lightless depths below, while his head has wasted away to a still-conscious skull.[2][3] It is rumored that his head is buried somewhere in the Mwangi Expanse, luring the serpentfolk to that region.[4] Whatever the exact truth may be, his clerics still receive his divine power, a sure sign that he has not followed Aroden into true death. A deity of unquenched passion and anger, the generally more cerebral serpentfolk used him as an example of all that was potent and primal in their psyche.[2] [3]

Ydersius is served by his still-active mortal kin, the serpentfolk, and an organization dedicated to bringing about his triumphant return, known as the Coils of Ydersius.[5]

According to the ancient legends of the Mwangi, the Zenj folk hero Old-Mage Jatembe learned secrets from the severed head of Ydersius, before sewing its lips shut.[6]
