Vual

Vual (also Uvall, Voval, Vreal, Wal, Wall) is a mighty Great Duke of Hell, commanding thirty-seven legions of demons.

Vual is depicted as a dromedary that after a while changes shape into a man, and speaks the Egyptian language, but not perfectly, with a deep voice.

He gives the love of women, causes friendship between friends and foes, and tells things past, present and to come.
