Qifrey may be mysterious, but I feel like so much of Olruggio's imagery is about how he hides himself. Like hiding behind curtains, the mask, even the beard.
Hell, who's the one who first taught Qifrey how to hide behind a smile?
It was Olly.
man how do you not look at qifrey and want to give him every single thing in the entire universe how do you not scoop him up carefully and just give him a little kiss on the forehead and tell him it'll be okay
