An ulitharid (noble mutated illithid)

A noble among your kind you have seperated yourself from the rest of your kind to focus on your own pursuits of evolution over sensless chaos. You stand 7ft tall but with the physiology to grow to 10 or shrink to 5. Your phase of self experimentation left your face smooth and womanly, lacking your facial tendrils as more have grown in the back of your head similar to human hair that touches the floor, despite repositioning you still have acute control of them and enough strength to bend steel. You don't appear to have a mouth at first but it has transformed into a maw of menacing teeth supposedly for gripping like a snake swallowing a rat rather than tearing and biting. Your mouth contains countless tongues almost as if all your mouth tendrils inverted. The horrors beyond your jaws are kept in check by a seamless seal that make it appear you had no mouth to begin with. You wear a more simplified version of the standard illithid garb consisting of a long black robe and colar with the exceptions of you wearing your collar down, which in hindsight looked ridiculous with the context of how many humans laugh at it...

Underneath your robes you are different and arguably improved compared to most illithids. You are now fit and muscular to dispatch almost any mortal foe unarmed with ease. You have grown a pair of D-cup breasts and a 2 ft ridged and knotted cock for when you work out generalized fertility for breeding an army of daughters. When you decided to love on your own you decided to adapt a decrepit manor into a lab and fortress. Rarely anybody comes here and the foolish few runaway screaming and occasionally limping with a sore ass. You are in the middle of perfecting one of your newest prodigal experiments. A brain beast that mutates its victims into your slaves slowly supplementing memories with psychic programming. Your working on its strong tentacled limbs to move swiftly into tight hiding spots.
