Jocasta is very short for a drow, but is extremely fleshily and bulgingly built, in a most un drow like way, with wide hips, huge protruberant G cup breasts, narrow waist, and a jutting bottom.  Her hair is silvery white, her eyes red, her complexion blue.  She has a lolth dedicatory tattoo spiderwebbing her torso, including her perpetually baldened pubis.  She starts play with an unmodified CHA of 15.  She is 120 years old.  She speaks common with an upper class dambrathan drow accent.  Her demeanor is hooded, evasive, hard to read.
