The Yuan-ti are a race of humanoids with snake-like characteristics. These include scaley skin, forked tongues, and black, beady eyes. The more powerful members of their race often invoke magical rituals to gain venomous fangs and serpentine bodies. The Yuan-ti are a secretive and hostile race, preferring to remain within their inaccessible cities, until such a time as they feel powerful enough to strike at other races with devastating effect. The most recent example of this occurred around 100 years ago, when the Yuan-Ti destroyed the Badger Hengeyokai town of Waxton. Since then, the Yuan-ti have only ventured from their capital city, The City of Fangs, to capture slaves or sacrifices for their dark gods.
It is rumored that the Yuan-ti have several powerful artifacts stored in the vaults beneath the city; trophies of the towns that they have razed. Some guess that this is the reason for the Yuan-ti’s attacks; that the Yuan-ti collect these artifacts. All knowledge about the Yuan-ti, however, is very speculative, few have the courage or desire to learn more of them.
Recently, more Yuan-ti than normal have been seen in the areas near Twin Sword Springs. A group of adventurers found a letter from the Yuan-ti promising they would help the bandit Chevkos when he attacked Twin Sword Springs.
