Prior to her contact with Dorzann, Nil was a normal human. Her exposure to an aboleth and her use of the psychic splinter has caused fundamental changes in her neurology and physiology. In essence, she is an aboleth-human hybrid. She looks normal-ish, except for the parts of her body that don't... look right.
As such:
- She can breathe both air and water and is an incredibly fast swimmer, able to out-speed sharks.
- Her skin is translucent in places, with her bones visible in parts. It is naturally slimy to the touch.
- She has a third eye centered horizontally in the middle of her forehead. She has excellent night vision, and can see in darkness as though it was dim light.
- Her open mouth is lamprey-like and her jaw is detachable. Her tongue has a pair of scissor-like appendages that can tear through soft things and she eats by grinding food with rows of serrated teeth. She could easily consume and swallow a whole pigeon if she wanted to (she does not.)
- She has two five-foot long tentacles extending from the shoulders behind her arms. In addition, her original arms and legs are unusually lithe and thin and appear almost like tentacles themselves. This is because
- Her bones are pliable and malleable. She can squeeze her body into gaps as narrow as an inch and can squirm out of most forms of restraint.
- She has a five-foot long tail projecting from the end of her spine which ends in a frayed fish tail. Naturally, this helps her swim.
While this does pose some advantages, she is very much alienated by her body and does her best to hide these features. The sheer amount of them, however, makes it a very difficult task to keep hidden from anyone with eyes.
