In Greek Mythos-themed poetry, the description of Nyx that stood out to me the most was that she was, literally, the shroud of darkness during the night. That she and Erebus blanketed the Day come nightfall. This descriptive imagery has inspired me to make her a being with a less distinct human form, and apply some level of inhumaness to her children.
Hypnos, a titular character in my story, was created to resemble a doll. In mythology, Hypnos is described as being a gentle god and sleep is a comfort to many. So I wanted his inhuman form to be something seen as positive and comforting, yet also harmless and even objectifying to portray how other gods view Hypnos. Despite him being a very powerful figure, he isn't treated as such in the modern day it seems. And even in classical mythology, rarely do we see him defending himself instead of hiding in Nyx's embrace. Dolls and other children's toys are also important archeaological finds as they show deep insight to day to day/personal life and other forms of artwork in the culture itself.
Articulated dolls have existed for millenia, much like Hypnos himself.
