Rab'ia al Fihri is a genie trapped inside of a prison bottle. She is an agent for The Peacekeepers of The Imperium where she works with Iskendriel and her handler, Isk[Tales 1]. Rab'ia was imprisoned for crimes by one of the genie kings, Al-Malik Al-Aswad, so that she can only use her powers when released from the bottle by a mortal being (citation needed).
