I would use them to be friend w some angel ocs that i have, their name would be Galeo probably!! English isnt my first language, sorry if my text looks a bit messy.
They would proobably be my sona's friend Gunther and a twin brother for Photographer ! Photo is an entity sent to manage artwork's worlds (long story short, in my universe each artwork has its own little world, Photographer must take care of those). But, said worlds in artworks are illegal, they shouldn't exist as a regular universe, lets say. Photo's job is to make sure those world only exist in human's mind, not as an active world of it's own. Then, Galeo comes to the table: they would be the one who gives life to these universes. They would be the entity who always tries to not let those worlds be JUST in human mind, somewhat a wanted being, but not really since there would (probably) be no proof of said acts. Photo prooobably knows it's twin is the one not letting these worlds be just in human mind, but im not sure. Don't get me wrong, but i don't want to write an entire lore w my ocs for a character i don't even know if I'll have at the end :'>
