Once human, yuan-ti histachii are near-mindless abominations who have been transformed into reptilian humanoids to serve their yuan-ti masters. Most often, they are found guarding yuan-ti brood chambers.
Histachii are hairless creatures. Their clothing, little more than filthy rags, hangs limply over their emaciated bodies. Their gray or yellow-green skin is tough and scaly, and smells faintly of rotting meat. They have beady, bloodshot eyes, and their forked tongues continually dart in and out of their mouths. Their dull yellow teeth are like tiny hooks, razor-sharp. Their fingernails are black and twisted, resembling the claws of a lizard.
Histachii attack any nonreptilian creature or humanoid on sight, unless their yuan-ti masters give them orders to the contrary. Unsophisticated fighters, most histachii charge directly at their opponents, attacking with their claws and teeth. To protect their yuan-ti masters, histachii will fight to the death.
Yuan-ti create most histachii servitors from human prisoners. They also may transform human worshippers who voluntarily agree to become histachii. Humans become histachii by drinking a distillation of yuan-ti venom mixed with certain herbs and roots. The yuan-ti prepare this special concoction. If a human is unwilling to drink, the yuan-ti pin their captive to the ground and pour the mixture down his throat.
Histachii are completely submissive to their yuan-ti masters, carrying out their every order without hesitation. The servants share the lairs of their yuan-ti masters. Usually, these lairs are in ancient ruins deep in tropical jungles, but sometimes yuan-ti dwell in subterranean caverns beneath human cities. A histachii’s duties include hunting, caring for the yuan-ti’s reptile menageries, guarding prisoners, and various custodial chores. In rare moments of leisure, the servants enjoy soaking in pools of cool water.
