Kathôl

Kathôl was a powerful mage who was able to transform into a black serpent as Sauron had. The Harad warrior was a master of poisons, magic, and melee. However, he met his end in the war against the Last Alliance. At the Battle of Dagorlad, he was struck down by Elendil, who severed his head with Narsil, the blade's flame cauterizing his wound.

Kathôl had tried to make a name for himself as a disciple of Sauron, often seeking people to worship him as they did Sauron. He tried to begin his own religion with himself as the main being of worship but this faith quickly died away when Elendil slayed the fiend.

In the end, the legacy of Sauron and Kathôl's forms would be instrumental in the traditions of the Haradrim for years to come.
