Siissyndolishulesh serves as one of the guardians of his Yuan-Ti nest, protecting the eggs of the community.  He rarely leaves the nest, spending his time supervising and training the brood-guards.  He won his position as Brood Supervisor by slaying his superior and taking his position.  In his youth he learned the skills of the samurai from a pureblood samurai.  He also learned origami from the same pure-blood who spent a lot of time in the Orient; Siissyndolishulesh still practices the art.  He is cruel and cold; violence is a way of life for him.  He is humanoid from the waist up, and is a snake from the waist down.  However, his torso is flexible like a snake, despite its humanoid appearance.  

Spell-like Abilities: 1/day – animal trance, cause fear, deeper darkness, entangle, neutralize poison, suggestion, and polymorph other as 8th level sorcerer (save DC 13 + spell level)

Psionics (Sp): All Yuan-Ti can produce the following effects at will.
            Detect Poison: As the spell cast by a 6th-level sorcerer.
            Alternate Form: The yuan-ti can assume the form of a Tiny to Large viper. This ability is similar to a shapechange spell cast by a 19th-level sorcerer but allows only viper forms. A yuan-ti in alternate form uses its most powerful poison attack if it has two.
            Chameleon Power: Yuan-ti can change their coloration to match their surroundings.
            Produce Acid: The yuan-ti can exude acid from its body, dealing 1d6 points of damage to anything it touches. The acid becomes inert when it leaves the yuan-ti's body.
            Aversion: The yuan-ti creates a compulsion effect targeting one creature within 30 feet. The subject must succeed at a Will save (DC 17) or gain an aversion to snakes for 10 minutes. Affected subjects must stay at least 20 feet from any snake or yuan-ti, alive or dead; if already within 20 feet, they move away. A subject can overcome the compulsion by succeeding at another DC 17 Will save, but still suffers deep anxiety. This caused a -4 reduction to Dex until the effect wears off or the subject is no longer within 20 feet of a snake or yuan-ti. This ability is otherwise similar to antipathy as cast by a 16th-level sorcerer.

Skills: Yuan-ti using chameleon power receive a +8 circumstance bonus to Hide checks.
