Yuan-ti

Yuan-ti are a species of monstrous humanoid snake-men and are usually of an evil alignment. Yuan-ti have their own language, and they can also speak Common, Draconic, and Abyssal.

Society
Yuan-ti call themselves vrael olo (which means "favored ones"). Daily use typically uses the shortened "vrael", and can be modified to "auvrael" (meaning friendly or known yuan-ti) and duthrael (unfriendly or unfamiliar yuan-ti).

In general, the more serpentine features a yuan-ti possesses the higher its status in yuan-ti society. Abominations are at the top of their society, followed by halfblood, and finally purebloods. Within their subraces, yuan-ti are ranked by achievements and the demonstrated favor of Sseth.

Most yuan-ti worship Sseth, with other serpentine deities that some have worshipped over the years either being masks worn by Sseth or a false deity of the Scaleless Ones. All yuan-ti must act in accordance with the Sacred Way of Sseth - that is, subtly. Whenever possible, yuan-ti choose manipulation over open confrontation, the whisper over the fang. Followers of the Sacred Way of Sseth know their foes, think ahead, and plan forward.

The goal of the Yuan-ti, as dictated by their demonic god Merrshaulk (also known as Sseth), is to bring about the ultimate destruction of the world.

History
Long before humans dominated the continent of Faerûn, the Creator Races ruled Toril. The reptilian Creator Race, the sarrukh, were foremost amongst these and built up great empires. They bred the first yuan-ti by magically experimenting with and breeding men with snakes. This way they also created naga, and through a similar process, lizardmen. They eventually fell from power and the resourceful yuan-ti rose up to claim their Creators' power vacuum, even while sustaining the empire of Mhairshaulk. Of the fragmented World Serpent deity that the sarrukh had worshiped, the yuan-ti venerated the strongest aspect, a cruel and despotic deity, Merrshaulk, who grew distant and aloof.

As the yuan-ti's power became less visible on Faerûn, and they instead fell to infiltrating human and demihuman society through their organizations and long-sighted plots, Merrshaulk had sunk into a slumber, ignoring his followers. Eventually, around the time of the collapse of the human empire of Netheril, Merrshaulk himself was also reborn as a winged yuan-ti avatar named Sseth, who became the yuan-ti's new primary deity. In the end, though, Sseth too sank into somnolence.

At this point some sarrukh, long suffering a heavy war on other planes or sunken in hibernation in their ruins, began to return in some numbers. They crucially needed help from their deity, but Sseth was not answering prayers in his slumber. So for aid in their endeavors some of the sarrukh made a bargain with the Mulhorandi deity Set, that put Sseth into a deeper sleep but allowed Set to assume Sseth's mantle and grant the sarrukh their aid. Most yuan-ti do not even know of this transaction, though now Sseth struggles at his bonds some are being made aware of it.

Life Cycle
Female yuan-ti lay eggs in brood chambers, marking each clutch with its parentage, then abandoning them to the care of broodguards. Yuan-ti hatchlings are hatched from these eggs, which are always curious and eager to explore, and will seek food immediately, even eating each other if sustenance is not at hand. Their initial training is provided by broodguards, which also monitor the hatchery. Young yuan-ti are trained in the use of their powers almost after being born. They will turn into tiny vipers and slither to the nearest cover when they see danger or hear a warning.

Yuan-ti in their prime will scheme, breed, and work on behalf of their tribes. Breeding is carefully controlled, seen as a holy act, in order to produce the "best" offspring. Prospective partners will coldly measure one another and if both agree that the match is promising, they usually mate, regardless of their personal affections towards each other.

Often elder yuan-ti grow lazy when they reach great age, sleeping or lying in torpor for longer and longer periods - first for days, then weeks, then seasons at a time, and finally years upon years. At last, they fail to wake at all.

Yuan-ti Breeds
The yuan-ti come in several distinct castes or breeds. The three most prevalent are as follows.


 * Purebloods: Appear mostly human, with minor reptilian features, such as slitted eyes, a forked tongue, or patches of scales on their skin. They serve as diplomats and infiltrators, pretending to be human.


 * Malison : Humanoid in shape but have a wide variety of noticeable serpentine features, such as a snakelike tail in place of legs, a complete covering of scales, a hood like a cobra, a snake's head, or snakes in place of arms. Malisons, also called halfbloods, serve as warriors and temple assistants.


 * Abominations : Almost completely snakelike, with only a few human features, such as arms or a humanoid head. They are the most venerated within the yuan-ti society, serving as clerics and in other roles of power.

Sub-breeds
In addition to the three main breeds, other breeds have been described as well:


 * Tainted ones: Human agents of the yuan-ti who have willingly undergone a ritual of transformation to make themselves yuan-ti, are known as tainted ones; they gain a venomous bite and slight psionic ability in the process. They retain their human appearance but often develop reptilian mannerisms, such as frequently licking their lips or drawing out sibilant sounds as they speak.


 * Holy guardians: A rare breed specifically bred as temple guards; they are also sent on missions to obtain needed goods for abomination priests. Holy guardians are naturally servile and follow their superiors without question. They uniformly have a serpentine tail in place of legs and a snakelike head.


 * Histachii: Also known as brood guards, these are humans who have undergone the ritual of transformation but have been found unworthy, degenerating into hairless, near-mindless reptilian monsters. The yuan-ti employ these wretches as watchers over egg-broods and other demeaning tasks.


 * Ignans: Another rare subspecies of yuan-ti that dwell in hotter climates of the world, including in volcanoes and on the Elemental Plane of Fire. Ignans are similar to yuan-ti malisons, except they are slightly more powerful due to some of the fire spells they wield.


 * Mageslayers: Another rare type of yuan-ti, mageslayers are bred for the special purpose of battling or hunting down human magic-users, and most of their abilities are magical rather than psionic. They have a human-like head but a snakelike tail instead of legs.


 * Anathemas: By far the most powerful and loathsome of yuan-ti, anathemas are worshiped as divine incarnations of Merrshaulk. They are truly bizarre in appearance, with a body like a 25-foot-long serpent; a pair of humanoid arms with clawed, three-fingered hands; and six serpentine heads rising from its shoulders.  An anathema's power dwarfs even that of an abomination, but since they represent such unfettered chaos, they are usually found away from yuan-ti cities, establishing cults that worship Merrshaulk through them.  They make a common practice of grafting yuan-ti body parts onto humans and other races for use as personal servants. Anathemas are extremely rare, however, and only a handful are likely to exist on any world.
