Useful to Genies. Occasionally, a djinn or other powerful genie may send a peri to deliver a message on their behalf. The peri treats such tasks as an opportunity to have some fun, often materialising in mid-air and bellowing the message at the top of its voice. Evil genies have been known to capture peris and keep them locked up in iron cages like little birds for mysterious purposes. Peris sometimes enlist the help of mortal adventurers in rescuing their captured compatriots.
