Dagoth (Conan Films)

From Multiversal Omnipedia

Dagoth, also referred to as the Dreaming God, was a deity worshipped by the people of Shadizar, particularly Queen Taramis. As written in the ancient Scrolls of Skellos, a jewelled horn placed in the forehead of a statue of Dagoth's human avatar would bring about the evil god's resurrection, and as long as a virgin girl was sacrificed at the hour of the god's rebirth (in this case, Taramis' niece Jehnna), everything would be fine.

Unfortunately, the ritual was interrupted by Conan and his companions and Taramis' priest speared by Zula before he could sacrifice Jehnna, and the end result of this is that Dagoth became angered and transformed into a monstrous, and mortal, lizard-like beast. The wizard Akiro deduced that Dagoth's horn was his life, and in tearing the horn from the ex-god's forehead, slew Dagoth.
