A fiend is an evil creature from one of the Lower Planes, also called the Fiendish Planes by some daemonologists. They are not just evil, but born of evil; primal malevolence is one of the roots of their nature, and the evil essence of the lower planes permeates every part of their bodies.

## Description

> "The left one was a hunched, reptilian beast with rippling muscle and palpable hatred. The right one was a cackling woman with dusk-hued skin and curled horns. The center one was a bipedal vulpine creature clutching a collection of scroll cases. They bared no similarities, bar the acrid stench that clings to such wretched creatures."

## Personality

> "Here's the thing about fiends. They're impossible to pin down. Some will enslave you. Some will manipulate you. Some will skip all the niceties and rip your arms and legs off. But don't forget, regardless of their approach, all fiends share one thing in common: their absolute disregard for your wellbeing. They don't love you. They don't care for you. They don't even acknowledge you as an insect. You're nothing to them. Your worth is measured in your use as a slave, or the taste of your flesh. The sooner you get that through your head, the better."

## Ecology

Not every creature from the Lower Planes is a fiend. Only baatezu, gehreleths, myredrioths, tanar'ri, and yugoloths are actual fiends in classic daemonological interpretation. In the broader sense, every outsider native to the Lower Planes and of an inherently evil nature is a fiend.

The life expectancy of a fiend is not known. A widely accepted fact about their aging process is that they do not mature. Those fiends that reproduce give birth to smaller versions of their species that grow bigger and stronger with time, but a fiend dying of natural causes or aging has never been observed. Because of this, it is assumed that they are immortal. It should be noted that fiends can techincally mature in a loose sense, as they rise through their respective hierarchies and evolve into stronger, more advanced forms. This is, however, a magical transformation and not some form of biological metamorphosis.

Most all fiends share a similar fundamental biology. They possess a form of circulatory system known as an Cordis Exterioris, or Outer Heart. Common among all denizens of the Outer Planes, the Cordis Exterioris is not one organ but rather a simplification of a universal trait among Outer Plane beings: their immunity to poison.
