Yuan-Ti are a race of serpentine humanoids not found commonly in the realm.
About
Yuan-Ti have great capabilities for stealth. Green skin and the use of war paint helps conceal some Yuan-Ti, while others have natural chameleon-esque camouflage capabilities.
Gods
Serket
An old holy leader of the Yuan-Ti who led them in Prehistoric times, Serket is typically considered a Lost God, with little appearance or interference in recorded history. Despite their disappearance, many of the ancient serpentine people (see below) still worshipped and waged holy war in their name.
Another theory holds that Serket was instead the Ta-Shedethen name for a still existing god such as the Yuan-Ti god Sseth.
Types
The Serpentine
The oldest Yuan-Ti ancestors, who originally slithered across Pteris, represent only a very small faction of the Yuan-Ti population in modern times.
Anathema
Terrible, unholy abominations, the Anathema are dangerous, nightmarish Yuan-Ti that look to decimate Quelmar. Often summoned or created as part of Yuan-Ti wartime, the Anathema were tanks on the Yuan-Ti battlefield, both immortal and magical. Since they were so unkillable, it was common for magicians to instead imprison or entomb Anathema into stasis. However, from their imprisonments, they could still occasionally reach out psionically, making contact with particularly spiritual creatures both underground like in Merca or on the surface.
Notable Populations
The City of Merca
A massive civilization of Yuan-Ti, and perhaps the largest single yuan-ti population in the realm, exists under the surface of the dunes of Pteris, notable for their moon-drawn lifestyles and their festival known as The Great Opening in which they emerge briefly at the surface up to 3 times a year.
Cof
A tribe of Yuan-Ti on the island Cof were notable for mixing their members with a group of Fire Salamanders, creating a new species of Yuan-Ti with heated bodies and fire breathing abilities. The Yuan-Ti lived in Cof's solitary mountain, living in caverns underneath of the island's guardian Chronepsis. While Chronepsis did not care much for the mixed race, they worshiped Chronepsis by sacrificing their elderly and bringing carved idols.
The leader of the clan Shaneeks was a full blooded fire salamander, but his two sons Silass and Mariss were half breeds that cemented Shaneek's control over the colony of Yuan-Ti. Shaneeks and his son would be hunted down by The Best Around on their journey to the top of Cof's mountain, looking for legendary crystals.
This colony also consisted of 98 soldiers, another 16 serpentine scouts, and a civilian population of 234. The population would come into conflict with the colonizers who invaded Cof, and would be nearly extinct by 700 PR.
