This is my personal creation! I'm calling them faux-sphinxes, creations of the god Chaos in mockery of the true sphinxes created by the first creator, Sol.
Sol covered our world with his creations, and all that breathed praised him. Sol's attentions thus turned away from his sister Chaos, who grew jealous without her favourite playmate, and so, she turned to other distractions...
I can't get into their lore a lot right now because OHMYGODIT'SONETHIRTYAMJESUSCHRIST and I need to go to bed, BUT, this is my personal Fauxsphinx, Bump. As in Bump in the Night.
Bump is a grumpy grump and here he is itching behind his...hand? I suppose?
Not sure.
Faux-sphinxes don't have true hands, rather they have proto hands. Their fingers only have the knuckle and a single joint, and their thumbs are just nubs. They don't use them much in the wild, but in the cities where some faux-sphinxes have been drawn, they tend to mimic whatever they see humans doing with their hands. Especially if they think it will get them food.
They're always hungry, and they don't care much what they eat.
