Fiend

> You think demons... are the only evil creatures that exist in Hell? Hell is infinite... there are more species of fiends.... than there are of Angels.

> Satan.

A **Fiend** is an evil creature from Hell, also called the **Lower Planes** in some cosmological models. 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 fiendish planes permeated every part of their bodies.

## Personality

Fiends lived long, and some had an inhuman view on time and life. They were capable of viewing a century passing by as inconsequential.

## Society

### Relationships

The demons and the devils held an eternal enmity for one another as they waged the Blood War.

### True Name

Every creature had a true name that made it possible for other creatures who knew it to gain control over them. For fiends, the true name was a double-edged sword. Knowing their own true name made it possible for a fiend to rise up the fiendish ranks, something that was very difficult for fiends without that knowledge. On the other hand, if knowledge of a fiend's true name somehow spilled out, it granted other creatures control over them. This control extended very far. For example, a mortal knowing the true name of a fiend could not only call it from the pits of Hell to the Physical World but also force it into servitude. Fiends could inconvenience or torment their rivals by helping mortals discover their rival's true names.

As mentioned above, a fiend needed knowledge about its true name to rise up the fiendish hierarchy. It often happened that the true name became different on changing form. It was believed that this was not the true name changing but some form of evolution of the true name. The core of the true name remained the same but there were some additions to it. When a mortal used an outdated true name to bind a fiend, the fiend responded to the binding. However, the control the mortal exhibited over the fiend was not complete and could have fatal consequences for the mortal.

### Mortals

> The first lesson you need to learn is that devils and demons are not at all alike. See, demons—they’re predictable. They come right at you, like bundles of white-hot rage-given fangs and claws. But a devil—he’ll be your friend, and like a friend, he’ll help you out of a jam, see. Need a few coins to get by? The devil’s got a few to spare. Need a warm body to fill your bed? The devil knows the best ladies. Want status? Riches? Property? Magic? Power? The devil has the answers. He’ll give you all you want and more. And what does he want in exchange? Just a little thing— a trifle, really. And it won’t affect you in the slightest. All he wants is your soul.

Mortals and the worlds they inhabited were often seen as useful by fiends, though this did not mean that they viewed mortals as having any intrinsic value. The value of mortals laid in their potential to be turned into fiends after dying. To do this, mortals were exposed to temptation by certain types of fiends. Otherwise, mortals were of use only as slaves, playthings, food, and mercenaries as far as the fiends were concerned. The Physical World was seen as a potential battlefield due to its lack of guardian outsiders, however, it was at its most useful when used as a generator of faith.

> I won’t tell you how I learned to bind the life force of a marilith to my own, but I did it just the same. See, I wanted immortality and riches beyond my wildest dreams. ’Course, I knew the fiend’s word wasn’t worth a speck of dirt, but I also knew she couldn’t refuse; after all, I held her life in my hands, right? Wrong. She took some of mine in return, and I’ve learned since that the immortality I was promised is eternal life as a dretch in her service. Sound like something a tanar'ri’d do? No, I didn't think so, either. See, I was ready for her to boldly break her word and try to squash me. I wasn’t ready to be peeled. But it just goes to prove my point: Every tanar’ri is an exception to the rule.

## History

The most important event in the history of fiends was the Blood War. The Blood War was an interplanar battle between demons and devils, which cost many lives. Thus, both sides were forced to figure out how to rapidly refill their ranks. The answer both sides came up with was to utilize larvae, which souls of evil mortals would become upon death. As larvae would turn into fiends, these fiends could be used to bolster the ranks of either army. Because of this, both demons and devils started to work towards turning mortals' evil.

## Ecology

Not every creature from the Lower planes was a fiend. Only baatezu, gehreleths, hordlings, tanar'ri, and yugoloths were actual fiends in the narrow sense. In the broader sense, every outsider with evil as part of its being was a fiend.

The life expectancy of a fiend was not known. An observation about their aging process was that they did not mature. Those fiends that reproduced, gave birth to a smaller version of their species that grew bigger and stronger with time, but a fiend dying of natural causes or just growing old was never observed. Because of this, it was assumed that they were immortal. One unique feature was that they changed from time to time into a different form. However, this was transformation and not some form of biological metamorphosis.

## Sub-Species

> Is one fiend eviler than the others? Depends on who you ask. Some might consider a quick death more merciful than prolonged torment. Some might think oblivion is much, much worse. Now, I’m not going to say which fiends I think are the evilest. That's a fool’s game.
