Iris, know as the goddess of the rainbow due to her multicoloured aura, is one of the Elders. She is very powerful, having access to the Shadowrealm waters of the River Styx. She was mentioned in The Sorceress, having given Nicholas Flamel two multicoloured friendship bracelets in return for a favour he did for her once. One of these was used to defeat the Hooded Ones, using the power of the River Styx to knock them unconscious for (according to legend) a year and a day.
- Immortality: Iris is Immortal and does not age. Though an immortal may be poisoned or slain in battle, they may live for thousands or millions of years.
