Simay Niazi is an interesting person. Sold into slavery as a youngster with the rest of her family, she did not take kindly to the idea and utilised her considerable abilities to do something about it... for she is a viskanya, a humanoid who produces natural toxins, and combines this with being a sorcerer of a serpentine bloodline!
After providing extensive background and other details, a complete set of stat blocks from level 1 to level 20 is provided. She's pretty potent even at low level and gets stronger especially when, at 3rd level, she adds a viper familiar.
Whilst not greatly blessed with full-on combat skills, Simay makes up for this with the subtlety of her magics. As such she could be a useful ally or even a recruit to a party of adventurers. Note however that she seeks to disarm and render harmless rather than kill, and whenever she encounters slaves is overwhelmed with a desire to free them. Still young, but alone in the world (apart from her companion viper) she seeks friendship as well as wealth from adventuring... and best of all, she's here complete, ready to use as a fully-featured NPC at whatever level you need her, or to provide a replacement PC should someone fall in battle.
