So something's been in my mind, and perhaps this is better suited for the theory thread. The non-humans characters we've met so far have been creatures of myth... except P. Like, Asterion and Storm are minotaurs (even if it's kinda pushing the definition of "minotaur"), Luke is a gryphon, Kota a eastern dragon, and even the cobalts are kobolds; P is like, just an anthro peafowl. Sure there are peacocks in myth but they aren't mystical themselves.
(Minor spoilers for The Hinterlands chapter)
There's the possibility, of course that P is from a race of or descendant of some mystical peafowl; but even so of all mystical peacocks that I know it all seems unlikely. There's Melek Taus (Yazidi) and Mahamayuri (Buddhism) which are both celestial beings so probably more like the gods that Asterion worships so the relation to P is very unlikely. Kartikeya's Mount (Hinduism) is peacock, it's part-demon and does make for a somewhat likely possibility. Finally there's Adramelech (Demonology / Christianity) which a part-peacock part-horse demon, this one is the most likely one in my opinion (AND would make for some fun irony given what Storm says when meeting him). Given that P is brazilian (or the least his grandpa was in Brazil), further complicates things as none of these are remotely from America.
(End of spoilers)
...Or y'know, he could be just a anthropomorphic peacock! I believe not being fully bound to "real mythology" is perfectly valid ( 'follow the fun' and all that). P's identity is mostly mystery at the moment, and I do think something related what I've been saying can be revealed. Being a fan of myth and such, that's the sort of thing that crosses my mind, I guess...
