Do you remember when being human meant you were normal? Probably not. It's been three hundred years since the last human without a “demon helper” lived. When the barrier shattered, it's just how things ended up. It's not all that bad though, trust me. I mean, at least we aren’t slaves, right? That’s usually how the story goes. You may not have a choice in having a demon attachment, but at least you still have… well. Your freedom?
1 | Every human is born with a demon attachment
A human born without a demon attachment in this day and age is unheard of.
2 | Pregnancies are rare
Successfully becoming pregnant often involves brokering deals with demons — particularly the one in your own body. After all, that demon will have to play nanny to another demon and share their space with someone else. Unwilling roommates? Yes. Some demons are more receptive, but most are like pissy cats that don't wanna share their host with another demonic entity.
3 | Humans live longer lives
Partially this is due to demonic aid in medicine, but much of it is also due to the mysterious process of ascension.

Demonic Attachment

No human is ever born alone. Whenever a human is born, a demon is ‘born’ along with them. Demons attach themselves to humans — demons get a free vessel to use as a battery, and humans get to be a little less average. It's great. Sort of. For the most part. While there have been various stories of human hosts and demonic attachments that don’t exactly get along, it is generally regarded as a symbiotic relationship. The demon protects its human host, and the human host gives the demon a means to enhance itself or otherwise harness greater power reserves.

Humans can only host one demon at a time and demons are classified as Primal or Civil. Every demon has its own Dominions and can gain more during its residency within its human host. Human hosts have the ability to acquire Ascensions, which further affect both the human itself and its demon counterpart. Sound complicated? Don't worry. Most countries around the globe include “demon care” in their curriculum, assuming the demon itself wouldn't inform you of all the details during the course of your life. Demons are chatty buggers.


The demons that exist independently only make up a quarter of the demon population, but to say they are potent and prolific is quite the understatement. Demons control things, but they still feed off humans. Violent demons might choose to eat, torture, or otherwise feast on humans in such a way as to live up to the legends of monstrous diabolical devils. Other demons, perhaps lesser known and often overlooked, prefer a more nonviolent take. They feed off dreams and emotions, but do not actually physically harm those they prey upon.
1 | Demons cannot dream
While this is a known fact, humans do not seem to realize the importance of dreaming to demon kind. The inability to dream means they cannot sustain themselves or their strength without preying upon those who can (humans).
2 | Demons can be born with or without a sex
Demons can be born as males, females, both, neither, or as something else entirely. It’s completely normal for a demon to not fit into a binary sex selection. Gender among demons is incredibly fluid and, just like in humans, often has nothing to do with whatever sexual organs they do or don't have.
3 | Demons do not reproduce sexually
Demons do not carry what humans refer to as gametes. Demons reproduce through a ritual, which means the sex (or lack thereof) of the participants is irrelevant in tracing lineage and parenthood. Creating a child invokes a pact in which no participant may harm any other physically, nor devour them. It is a magical process and it's magic that ties a demon's hand. For that reason, demons are circumspect about invoking the ritual and creating a demon child.
4 | Demons must feed off humans
Be that their flesh, blood, or other physical component… or their thoughts, memories, emotions, dreams or other incorporeal component. Different demons feed off different aspects.
5 | Demons are innately cannibalistic
Demons don't like other demons. Demons can eat other demons to gain their dominions and memories and to enhance their own masteries. Competition among demons is pretty high, and demon society is pretty ruthless.
6 | Demons are believably 'immortal'
Humans don’t really understand the mechanics or nuances of the theory, but the easiest translation is this: demons are recycled. When they die, they are born anew, be it soon after their death or centuries later. Demons will rarely remember their past lives completely (though some dominions specialize in uncovering such ‘reincarnation’) but any given demon has likely lived many different lives.

Demons: Primal or Civil

There once raged a massive debate among humans in regards to which demon type is superior. Hell, there still is. But if you ask the demons themselves, they'll gladly inform mankind of their ignorance: primal demons and civil demons are merely two different extremes. Humans have very little choice as to which sort of demon they're saddled with at birth. All human hosts appear to be born with primal demons, but within the first years of the host’s birth, the demon will begin to show civil tendencies (and become civil) — or never do so.
Primal Demons
Civil Demons
Primal demons appear to have the intelligence of predatory birds, but appear to lack the mental ability (or willingness) to grasp more difficult tasks. Similarly, though primals cannot speak a language, they do communicate with their hosts as animals or beasts in the mortal world would and have the capacity to converse with other demons. Primal demons often occupy less humanoid appearances, assuming they manifest at all.

All human hosts are born with what seems to be a “servile” primal demon. At one to three years of age for the host, the demon will show civil tendencies. If they do not, they will remain primal.

Primal demons are believed by humans to be weaker attachments than civil demons, but among demonkind, primal demons are viewed as being more feral and incorruptible.
Civil demons are more akin to humanoid companions. They often engage in speech and discourse with their human hosts and — should they be strong — will often seem to be fully-fledged individuals of their own. They are, however, still tethered to their human host. Civil demons tend to manifest appearances.

Civil demons will develop and appear to be separate entities. They have the capacity to form their own relationships, thoughts, emotions, agendas, and personalities. Civil demons rarely share the age of their host.

The appearance of the civil demon can be affected by a human’s strong affinity towards fictional or historical figures, or may otherwise fashion an appearance realistic or fantastic.

Demon Reproduction

While humans have difficulty conceiving due to their demons, demons have their own "reproductive" challenges. They may reproduce with other Solo, Civil or Primal demons, provided the demons agree to it, though some do more easily than others. Under no circumstances can Solo, Civil, or Primal Demons reproduce with Humans.

— The desire to reproduce greatly differs from demon to demon, and while some may do so in pursuit of company others may do so for the express purpose of expanding the chaos they cause.

— The contents of these rituals vary from pair to pair, but regardless of the specifics, each demon must contribute part of their essence for a ritual to be successful. Other than this, the rituals and what articles, components, and locations of them are widely varied and can be chosen by the participants themselves.

— Offspring, once made, are but a ball of light and retain this appearance until they decide on a form and have their first meal. They are fully functional and mature entities at birth and therefore do not require physical maintenance from the parent demons.

— The dynamic between parent demons and their offspring are greatly varied and depend on the demons involved. For example, they might take after more permanent human relationships or they might all part ways the moment the ritual is complete.

— Demons can choose to portray any initial age they wish and alter it over time. While the parent demons can easily part ways without needing to nurture their offspring, a new demon is not omniscient and must learn of its world the way anyone else might.

— Upon the conclusion of this ritual, demons may register their specific, individual, and unique agreements in the Demon Contract Reproductive Registry.
Solo Demons
Civil Demons
Primal Demons
Solo Demons reproduce most easily with other Solo Demons, but relatively easily with Civil and Primal Demons, as well.
Civil Demons may reproduce with Solo, Civil or Primal demons with moderate ease.
Primal Demons will more easily reproduce with other Primal demons than with Civil or Solo Demons, which can prove more challenging.

Demonic Appearance / Personality

It was once believed that demons were the manifestations of the subconscious of their hosts. While this has grown to be an unpopular opinion, evidence exists that the human host’s psyche does affect the appearance and personality of the demon attachment as much as the demon attachment affects its host, at least to some extent.
Types of Appearances
Humans with strong affinities towards fictional characters (or demons who have been exposed to such affinities in previous lives) may become hosts to demon attachments that embody the canon of these characters.

Likewise, humans with strong affinities towards historical figures (or demons who were perhaps exposed to such historical figures in previous lives) may become hosts to demon attachments that incarnate the nature of these figures.
Demons may embody creatures and beasts that may be fantastic, exotic or common in the case of Primal Demons or may take the form of humanoids realistic or otherwise in the case of Civil Demons.

Demons often manifest in one particularly stable form. This form may change when a human experiences an ascension change, but will otherwise be fairly reliable.

Human Ascensions

Humans can ascend, though how often this mysterious process happens appears to be based on how they live their life: the relationships they form, the risks they take, the changes to themselves they pursue or enable. There are a few things that are known, though.
Ascension Information
Some people never ascend. Some people ascend so quickly they hoard ascensions.

Demons have told us that the basic ascension paths are linked to actions, not fate. Because of that, a prominent demonologist who was a tarot reader ironically named the different known or speculated paths after tarot cards, names which stuck.

Each tier of ascension gives a human host another 25 or so years onto their natural lifespan. Note that a violent death will still kill them, just not the natural process of aging. This doesn't get tacked on to the end, or allow someone to regain lost youth: rather, it becomes as if, from that point their maturation was at, they started aging as if they had 25 more years elongated over the rest of their human life. If you were 25 at your first ascension, you'll look under 40 when you're 50. If you're 60 at your first ascension, you'll still look under 70 when you're far older than that.

Ascending at higher tiers allows a human to change shape into their ascension form. All aspects of an ascension form don't have to be kept (you could, for example, keep the animal ears but not the matching tail). When you go beyond that ascension's basic path, reaching say tier 4 after tier 3, you lose tier 3 of that path's ascended form and ascension. You may refuse to follow the roads placed before you. If you do, you must do something worthy of ascending again in that path to achieve another chance to ascend. Choose wisely.

You can follow more than one ascension path, but you cannot gain 25 years to your lifespan unless you reach a higher level than you’ve reached in another ascension path. 10 ascensions won’t get you 250 years to live, and certainly not if they’re all at tier 1, as demonologists mark it. But when you ascend past the first tier in any of those ascensions, you will now have another 50 years to live.

Ascensions are also known to affect demons, amplifying their power over some of their dominions and sometimes changing their form, particularly primal demons.

Ascending is viewed by some as the key to immortality, to a human living an eternal life. No one knows how high the levels of ascension grow.

Ascensions and gaining new dominions only happen organically. You can’t farm for ascensions, though believe me, people have tried. If you genuinely improve or debase yourself, you are likely to ascend or gain the plant dominion. If you interact with flowers in ten instances, that won’t give you the plant dominion. Seek to better yourself — or worsen yourself!
