Uterus

A mechanical puppet resembling a medical mannequin, the Uterus carries an embryo within it that will crawl out to attack the player. Like other creations of Valteil, Uteri are soulless.

It's suggested that Valteil uses them to satisfy his own needs, and possibly using the Embryo too in his depraved acts, since Nas'Hrah suggests Valteil is a pedophile.
