For the book series, see The Demonata

The Demonata (demons) are creatures who have no feeling or emotions and can kill humans or even each other without regret. They generally take forms combining aspects of many animals from the human world since they lack creativity. They like nothing better than to eat and kill humans.

The Demonata

Lord Loss (book)

Only three Demonata appear in this book, Artery, Vein and Lord Loss

Demon Thief

Many years ago, a few mages came up to the legendary Beranabus and asked him to form an alliance group to fight the Demonata. At first, Beranabus was reluctant but later he just let them go on and do what they want, keeping in touch with only a few of his Disciples at a time. Their main job was to stop crossings into the human universe but a select few traveled around with Beranabus in the Demonata's universe to try and find the legendary universe destroyer, the Kah-Gash.

Slawter (book)

Lord Loss appears in this book , along with a demon that looks like an ant .

Bec (book)

With the help of humans and other intelligent beings, they moved onto planets in the other universe and killed just for fun. Later, when the humans needed to keep their numbers up, they mated with the Demonata and hence, the Grady curse was made.

Blood Beast

For the entire chapters there are no demons except in the end of the chapters.

Demon Apocalypse

In this book, the Demonata break through to our world via a tunnel, and soon slaughter everyone on it except for a few. When the Kah-Gash sends Grubbs, Bec, and Kernel back in time, they close the tunnel after a battle with Lord Loss and Death (aka "The Shadow").

Death's Shadow

Wolf Island (book)

Dark Calling

Dark Calling reveals that both the Old Creatures and the Demonata are creatures of the original universe which preceded the two universes in the series. This universe was structured like a chessboard; it consisted of sixty-four squares, half of them White and half of them black, each square containing infinite space within. The Demonata inhabited the white squares, the Old Creatures the black; the different zones were kept separate by a force which the Old Creatures called the Kah-Gash. While the Demonata were capable of reproduction, the Old Creatures were sterile, but this did not bother them; since time did not exist in the original universe, everything therein was ageless and immortal. They can still get killed.

Originally, the peaceful Old Creatures contented themselves with exploring their realms, undisturbed. The Old Creatures and the Demonata were unaware of each other, and it is stated that they were never intended to mix. However, out of curiosity, the demons eventually crossed into the black zones, discovered the Old Creatures, and attempted to wipe them out. At first the Old Creatures fled, hoping in their innocence that the demons would lose interest and leave them alone. When it became clear that this would not happen, the Old Creatures were forced to engage the demons in open war.

As the conflict escalated, pressure was put on the Kah-Gash, and it ultimately fractured under the strain. When this happened, the entire universe collapsed into a single speck, exploding a split-second later in what came to be called the Big Bang. The explosion formed two new universes: one (this universe) for the Old Creatures and ultimately the numerous species which developed on various planets; the other for the Demonata. The Kah-Gash split into three pieces, which for the next several billion years moved between the two universes inhabiting various life forms. Its last act was to create structures separating the universes, so that the two groups would never come into conflict again.

Following the explosion, time came into existence; everything in both universes began to age, and therefore became mortal.

Hell's Heroes

After the Kah-Gash had been unleashed and the universes were both destroyed, Grubbs Grady, Bec McConn and Kernel Fleck traveled to the Crux to finish off the Demon Masters for good. There, they wiped out the entire population of Demon Masters except for Lord Loss as Bec had struck a deal with him to keep him alive. Hence, all Demon Masters had been killed meaning very limited or no crossing in future after the universe had been recreated.


The Demonata are an unimaginative race. They steal their shapes off of other creatures from the human universe. Some, however, just take on random forms that no one can name. Demonata vary in size, from the size of bugs to demons the size of stars.


The Demonata are generally cruel and only want to kill. However, some demons such as Lord Loss instead feed on the misery and suffering of humans. The Demonata are not, by nature, playful creatures, but Lord Loss is an exception as he plays and loves chess almost as much as he loves humanity's sorrow. Demons kill both for fun and to further their goal of wiping out all life in the universe's white zones.

Demonata somewhat respect the Old Creatures, though they are bitter enemies.


Demonata can be split into several ranks from weakest to strongest: the Fomorri, normal demons, and demon masters.

1st tier Demonata (The Fomorii)

The Fomorii are what the ancient people of Ireland thought were the worst of all demons, as evidenced in Bec. They were weakened by sunlight and usually attacked at night. However the Fomorii were mostly weaker demons, and would often merge their bodies with those of the human dead and animals before fighting others. Fomorii were capable of being killed without magic, allowing human warriors to fight them off temporarily. They are named after a race of demonic creatures from Irish legend.

2nd tier Demonata

The middle tier of demons vary widely in size and strength. Some are tiny and others the size of stars. All of them are deadly, however. They can only be killed by magic, and will simply regenerate if destroyed by human weapons. However, they generally cannot survive without a source of magic nearby - they quickly fall apart in the human world if their portal closes. They tend to have animal qualities. Some serve demon masters. Lots of 2nd tier demons tend to dwell inside their own universes with demons of a similar type. 2nd tier demonata are likely the most common, dwelling in many universes in large numbers. Such examples of 2nd tier demons in the book would be Vein, Artery or Gregor.

Demon Master

Demon Masters are the most powerful Demonata of them all. They are so strong that they can kill even the most powerful of magicians easily. Each Demon Master usually creates their own realm in the Demonata universe to live in, sometimes with their familiars. Some Demon Masters can also lay dormant until requirements are fulfilled, such as sacrifices. Lord Loss is one of the weakest demon masters, and is still capable of easily defeating most characters in the series. Like lower demons, demon masters seem to combine parts of multiple animals from the human world to form their bodies.

Lesser Demons

Lesser Demons are the most reoccurring demons seen throughout the series, as none of the other demon masters have the powers to open windows to send their familiars through withough the help of a maage, or a lode stone. This would be because they never harnessed the Kah Gash or a piece of it before, like Lord Loss did.
