Upon viewing Ashad manifest over Lake Geneva, Percy Shelley described what he saw as a "death god rising from Hades". (TV: The Haunting of Villa Diodati)

Much like other deities, death gods had their own alien dimension separate from the universe. (COMIC: Cindy, Cleo and the Magic Sketchbook, Old Girl)
