Out of the Darkness and Into the Light
The jann (singular janni) are the weakest of the genies. Jann are formed out of all four elements and must therefore spend most of their time on the Material Plane.
Jann are physically strong and courageous, and do not take kindly to insult or injury. If they meet a foe they cannot defeat in a standup fight, they use flight and invisibility to regroup and maneuver to a more advantageous position.
