Archives of Nethys: Ifrit
Ifrits descend from creatures such as efreet, salamanders, and magma dragons. Their spark of ancestral flame gives them a reputation for being passionate, if not capricious.
Ifrits often build up personal relationships between themselves and the idea of fire, feeling as though they embody it mentally or spiritually, in addition to physically. Some ifrits relate to fire's mutable energy, illuminating properties, or destructive nature.
Some ifrits share a connection from birth to specific aspects of elemental fire, such as radiance, ash, or lava; this is called an ifrit lineage. Ifrits often have the same lineage as their parents, though sometimes ifrits are born with lineages different from their families, or to parents without one. Lineages can appear in ifrit children as a reflection of where they were born—for example, cindersoul ifrits sometimes originate from being born in areas prone to forest fires. They can also occur as a reflection of the ifrit's planar ancestry, such as a brightsoul ifrit having a fire-themed celestial ancestor like a peri. Magma ifrits with the lavasoul lineage are most often born the descendants of magma dragons or other lava-themed fire elementals.
