Galadria, the Voice of God

Galadria was once a queen who convinced her subjects her majestic voice spoke the word of a deity and used her talents to bring war. Her voice is now cursed to only brings literal death and destruction to those who hear it- ensuring she only speaks to her foes and criminals about to be executed. She otherwise communicates her manservant via a telepathic link.

Inspiration for this character comes from Marvel Comic's Black Bolt and God as depicted in the film Dogma.
