Abomination Race Details

With a sickening crunch, his bones broke and his flesh split. He screamed his throat raw as the transformation took him, and then where once stood a man, now stood a beast—a lurching, clawed monstrosity. I saw by the malice in its eyes that a ravenous hunger lived within its blackened soul, and all mercy had been purged. It had taken several years, and the lives of many, but I knew then I had finally created the perfect predator.

Abominations are humanoids, dwarf, human or otherwise, that have been subjected to a harrowing ritual and forever changed. They may hide among society in their humanoid form, but a monster lives within the abomination, able to transform into an unrivaled predator. No two are alike, save for the unrelenting hunger that lurks within, urging them to violence. Some embrace it, others rail against the bloody cravings, but all suffer from its burden.

Eldritch Transformation

Long ago in a bygone age, a dark wizard sought to forge the ultimate minion. He gathered the most powerful creatures he could find, from werewolves to trolls, and took their most potent traits. In one abhorrent ritual, the wizard fused them all together within a mortal's body. The result was a disfigured man, scarred by a hundred eldritch runes, with the ability to undergo a brutal transformation—he could change into a monstrous form at will, which reflected the creatures he was wrought from.

And so the first abomination was created. Swift, strong, and with a deadly intelligence driving its viciousness.

Since then, many dubious spellweavers have since attempted to recreate the ritual, but only the most ambitious and depraved have succeeded. Each abomination that lurks among the lands is a product of one such effort, whether they were an unwilling victim who survived and escaped, or else a willful volunteer seeking the power it would give them.

The Beast Within

The basic nature of the abomination's original race will have been wiped away. Although their true form remains humanoid, appearing as a human, elf, or otherwise, they lack its traits, and in their place have unnatural agility, strength and cunning, along with the ability to shapechange at will into a monstrous form, reminiscent of lycanthropy. Their humanoid form is likely scarred—typically by experimental wounds, or the ritual branding of sorcerous glyphs. 

The monstrous form of an abomination can take many varying appearances, with each abomination created from a different combination of creatures. Some might have jagged fangs and leathery wings, others claws and a canine snout, whilst there are also those with a chitinous carapace and burrowing claws. Once you've selected your traits from the options, decide with your DM on your monstrous form's appearance. Some resemble were-creatures, whilst others are uniquely grotesque. Some are even blessed with only subtle visible changes, with the abomination still appearing mostly humanoid, although this is extremely rare.

Ravenous Hunger

The one defining trait between all abominations is the bloodlust that affects them, regardless of what form they currently reside in. Those who embrace it are inevitably evil, prowling among civilized society like a wolf among cattle. There are those that resist it, if with difficulty, eking out a living in backwater villages, or as hermits keeping themselves away from those they might otherwise harm.

A rare few abominations can, through a steel will and great effort, redirect this terrible thirst into something productive. They vent their need to rend flesh by targeting not victims, but other horrors, often keeping their true nature secret and gaining great (and ironic) repute as monster slayers. 

This hunger is not truly physical, in that an abomination does not necessarily need to eat its victims. The need is to cause pain, harm, and ultimately something's death. The hunger can be sated, but only briefly, and the longer an abomination goes without harming something, the more irritable and uncontrollable it becomes. Sometimes an abomination can go without harming a creature for weeks, others need to strike every other day, depending on what kind of monsters they were made from, and the manner of the ritual that changed them.

Regardless, a revealed abomination is a horror to the common folk of almost every race, if only for being mistaken as a werewolf, vampire, or other known monster.

Abomination Names

Most abominations keep the name they had in their life, prior to gaining the ability to take on a monstrous form, having a name from their basic race (human, elf, dwarf, etc). Those who embrace the change may take up a moniker to symbolize their new, dark nature. Others find themselves unable to remember their name, suffering amnesia from the immense magics put upon them, and cling to the first name they're given by another.
