Archives of Nethys: Sylph
Sylphs are an intense and lively people, flighty and tempestuous. These planar scions have kinship to beings of elemental air such as djinni, invisible stalkers, and cloud dragons.
Sylphs enjoying following their own tempos, shifting between wild energy that draws all eyes to embodying the spirit of unseen breezes that slip away without note. They often build their identities around their perceived personal connection to the element of air, relating to a gentle breeze, a sudden flash of lightning, or an uncontrollable storm.
Some sylphs are born with a connection to an extremely focused aspect of elemental air, such as smoke, storms, or toxic gas. While it does happen, a child is rarely born with a lineage that differs from their parents', as geniekin typically pass these unusual gifts on to their offspring. Lineages can manifest in sylph children as a result of where they're born, such as when stormsoul sylphs are birthed in regions prone to tornadoes or windstorms. A lineage can also reflect a sylph's elemental heritage like in smokesoul sylphs, who often descend from belkers. Fumesoul sylphs, on the other hand, are associated with poisonous and otherwise unbreathable gases.
