Orobas was a demon and prince of Hell.
In the 19th Century the demon was summoned by Gustav Strobl in an abandoned cathedral in France. Strobl originally thought Orobas was Satan himself, and begged the demon to led him lead Satan's army during the apocalypse. Orobas laughed at Strobl's request, stating that he can offer only Earthly gifts.
Following the death of Satan, Orobas was one of the many demons killed in Hell's civil war, alongside Beleth, Shax, Amdusias, Rumael and Moloch.
