Daemons are the servants of the Dark Lord, the ruler of the ikarian realm of Abyssos - one of the most fortified, inhospitable and inaccessible of the ikarian realms. They have ever served the Dark Lord, and do so with a fervour that surpasses the most zealous mortal races, with all daemons being unerringly loyal to the Dark Lord. There are many types of daemon - from succubi and incubi to the ever-infamous Abyssal Daemon, and many more besides - but all of them are unified through one element: their shared access to dark magic.

Daemons are most famous for their dark magic, which they exhibit exceptional skill in. Dark magic itself is a very weird thing, as it exists as a perversion of the System's own mechanics that is maintained by the Dark Lord themselves. Nobody knows why the System doesn't purge it, but it definitely doesn't. Daemons are able to almost psionically teach mortal races how to use dark magic without spending years to learn traditional system magical techniques, and exposure to it gives a myriad of benefits, as well as drawbacks, all covered on the dedicated System Magic article. Daemons themselves, as favoured kin of the Dark Lord, are not impacted by the drawbacks of Dark Magic, allowing them to fully exploit it.

Perhaps the most infamous type of daemon for its biological traits is the Abyssal Daemon, however, which stands as a titanic 25-foot tall monster designed by the Dark Lord as the daemonic counter to the Aggeloi following their defeat by one such Aggeloi during their invasion of Pearalos. Equipped with nigh-impervious daemon-steel chitin and suffused with so much dark magic that they're a danger even to daemons, abyssal daemons are effectively daemonic superweapons, deployed in response to the Aggeloi... and for all their strength, being truly terrifying to behold, the Aggeloi have consistently proven to be the far superior bioweapon.

Daemons are extremely aggressive and manipulative, aiming to corrupt and coerce any mortal they encounter into adopting dark magic, and where devils use guile and words, daemons are known to prefer either seduction and indoctrination - in the case of succubi or incubi - or brute force to get their way. Their ultimate goal is to spread chaos and destruction within Pearalos, as they delight in chaos, as well as the destruction it inevitably brings with it.

Daemons are frighteningly intelligent, so much so that even the most intelligent mortals are profusely cautious around them; they know exactly how to get what they want, which ironically makes their very aggressive and 'full-frontal' general personality a blessing, as it prevents them from being more conniving and dangerous than they already are...

And that is why succubi in particular are among the most dangerous type of daemon, as they are the favoured daughters of the Dark Lord, and that status has them known for being far more cunning, conniving and willing to use their frightful intellect to forward their sire's goals, with incubi as a close second in this regard, though they are known to not be as favoured by the Dark Lord.

One of the most dangerous aspects of daemons is their ability to directly perceive mortals from huge distances, often from miles away, and perfectly trace their every move. Only the best mortal mages can cloud the mortal-sense of a daemon, as only they generally have the means to sense that a daemon is stalking them in the first place.
