The Doll Life Ending is an Ending in Prisoners of the Elder One. It occurs after performing the complete ritual in the Nexus Crypt.
A ball-jointed gothic lolita doll is summoned, and Erik is pulled into it, transforming into a life-sized version of the doll. The Elder One promptly steals Erik's soul, rendering him fully subservient for decades, until another trespasser restores her autonomy. Even then, Erik sees herself as a doll, and leaves with the newcomer to serve him. This is quite similar to the Vicky True End, with roles reversed.
