Embodiments of Sin
A demon eidolon's shape mirrors the summoner's own sin, so greed might conjure a nalfeshnee while stranger sins summon something unrecorded.

While all demon eidolons have an associated sin, those sins can be incredibly varied. While many demon summoners conjure up easily recognizable eidolons, such as tempter demons appearing in the form of seductive succubi or wrecker demons taking on the form of destructive abrikandilus, other demons may also answer the call, including ones no one has ever seen before on the Material Plane. A greed-filled summoner might find that their eidolon is in truth one of the fearsome boar demons known as a nalfeshnee, while a summoner whose secret sins are stranger and darker than the average person might ever contemplate could conjure up a demonic presence whose appearance has never been recorded in the history of the mortal world.
