The Daughters of Eigenwald, or Does for short, were created by Staunt von Eigenwald to be his personal servants. Many of them are still living at his castle doing his bidding, but every so often someone from the outside will conduct a raid on the forest, both to stop Staunt's latest scheme and to incidentally free as many of the Does as they can find. Once they're brought outside the forest, free will kicks in and they get training in any discipline they decide to take to.
The Does don't age, and have superhuman strength and speed, but are entirely emotionless, experiencing neither pain nor pleasure, and totally sexless. Many of them have custom-built body shapes (like the one on the right there), but they all look roughly the same.
