Archives of Nethys: Suli
Sulis are geniekin who embody a mixture of elements, most commonly air, earth, fire, and water. They are typically the descendants of jann, genies of all four elements that wander the Material Plane instead of making a home on the Elemental Planes.
At birth, a suli resembles their mortal ancestry, not manifesting their otherworldly heritage until adolescence, when they awaken into their elemental power. Strong in body and will, sulis are dynamic and ever-changing, and most feel they embody either all the elements together at once or the traits of different elements at different times. Some see themselves as having multiple aspects or faces to their personalities—one for each element—that they cycle through over the course of days or weeks.
