Iris comes from Greek, named for the goddess who carried messages between gods and mortals along the rainbow, and the name is traditionally associated with communication and connection across distance. It's often read as suggesting someone who bridges different worlds rather than staying fixed in one place.
Always deliver judgements from the Stars in general terms, or if thou dost otherwise let it be when thou hast very evident testimonies and in great and weighty matters. - Cardan Girolamo (1501-1576)
