Jeweled Horn of Dagoth

The Jeweled Horn of Dagoth is an ancient artifact and the missing piece to the dreaming god Dagoth.

Conan The Destroyer (1984)
According to the Scrolls of Skelos, a young virgin woman bearing a specific mark was to be sent on a perilous journey in order to procure a key to the temple where the horn was kept. The scrolls then said that the one who procured the horn was to take part in a ceremony which would lead to the woman's sacrifice in order to raise the god Dagoth from his slumber.

Queen Taramis was determined to obtain the horn, as her niece Princess Jehnna possessed such a mark. To succeed in this, the queen needed the help of the Cimmerian Conan. Conan agreed and traveled with Malak, Akiro, Zula, Jehnna and Bombaata to retrieve the key from a castle guarded by a wizard. Once they obtained the key, they headed for the temple where the horn was kept and Jehnna retrieved it before returning to Shadizar with Bombaata.

With the horn placed in the forehead of Dagoth, the sacrifice almost occurred, but Zula impaled the wizard before the princess was killed. This in turn angered Dagoth and he began wrecking havoc in the palace. Akiro told Conan that he must pull the horn from the forehead of Dagoth in order to kill him, which Conan managed to do and killed the god.
