This is Beleth. According to Christians, this is a demon
TERRIFYING!!!! π±π±π±
When appearing, he looks fierce in order to frighten the conjurer or to see if they are courageous. The conjurer must be brave, and hazel wand in hand, must draw a triangle by striking towards the south, east, and upwards, then commanding Beleth into it by means of some conjurations.
There's a whole thing with owls being spooky. One of athena's symbols is the owl, which is funny because they're canonically dumber than paint (no offense). I think in Latin or Italian owls are called "Strix" or something like that which is related to "striga" and a whole bunch of other words for wishes.
And then in north America there's a couple of indigenous cultures that have some kind of beef with owls but I don't recall the details.
