Hadasha Nisuvi
Hadasha was one of the infamous Enkidu’s projects. Whether she was stolen from some unfortunate mother, or created in a lab is unknown, but she was recovered in the aftermath is unknown. What is known is that while she is almost painfully bright, she is also almost painfully socially awkward and nowhere near her apparent age. She is extremely fast - and that extends to her development, as near as they can figure she may actually be closer to twelve than her apparent fifteen. No one truly knows.
(As a note, if someone wanted to ‘adopt’ Dash and fully develop her as theirs they are welcome to.)
