Seraphim (or simply Seraph) are another one of those bizzare-yet-cool types of angel. They are usually associated with fire, hence the blazing corona. And they have six wings, one pair of which covers their face, another pair their feet, and the last set to fly on.
Which always made me wonder why, exactly, they could only properly use two wings. Were they shy? Is that why their faces had to be hidden? Maybe they had bad hair days.
Fortunately, we now have things called ‘masks’ or, in the latter case, ’hats and detangler’. And maybe they could get a nice pair of boots and not worry about the whole cover-your-feet thing (which my guy here seems to have forgotten about). And then those extra wings could be used for, y’know, flying, like they were intended.
