I came across this,eros is in association with chaos and eros's consort is psyche(soul/breath of life)(also butterfly, is that why genshin has so many butterfly refrences??)

Could pneuma/ousia be related to ether/void mentioned in the Byakuyakoku Collection?,aether body has relation to breath,but i couldn't find anything on void/ousia(but ether is called the 1st element does that count as 'essence'?)
