Iris is the Goddess of the Rainbow. She carries messages for gods, goddess, and if you ask nicely and she's not too busy, to demigods. To Iris Message (IM) someone, you must find or make a rainbow (easier in modern times with the advent of the water hose) and throw a drachma through it, then say: "O, Iris, Goddess of the Rainbow, accept our offering." and name who you wish to speak to and where they may be found. this is all lies, just to let you know!!!!!!!
