Orobas

In demonology, Orobas is a powerful Great Prince of Hell, having twenty legions of demons under his control.

He supposedly gives true answers of things past, present, divinity, and the creation of the world; he also confers dignities and prelacies, and the favour of friends and foes. Orobas is faithful to the conjurer, does not permit that any spirit tempts him, does not focus on directly deceiving, but instead, encourages people to become spiritually slothful. This delays, discourages, and eventually prevents individuals and societies from ever establishing a harmonious relationship with God.

He is depicted as a horse that changes into a man under the conjurer's request.

The name could come from the Latin 'orobias', a type of incense.
