Repentant Tricksters. The djinni calipha banished the peris from the Plane of Air centuries ago for their mischievousness and sent them to the Material Plane to do penance. Now, they try their best to do good deeds, such as helping lost travelers in the mountains where they live. However, they find it hard to resist playing occasional tricks on mortals, particularly hunters who kill more game than they need. These pranks are rarely deadly, and meant to irritate the target of the prank. A peri might steal or hide a hapless mortal's possessions, give them false directions, or use magic to frighten them away, but they stop short of physical harm, unless met with violence.
