Valeram is able to change their appearance to make moving among humans easier. Their shapeshifting skills are not good so they can only change their head and skin color. Body shape (wings included) will always be the same. Valeram works in a local temple as priest (simply because the priest robe is ideal for hiding wings and body shape).
Valeram eats only human hearts and their only purpose is to make deals with humans, Valeram does something for human and in return the human must give their or someone else’s hear for Valeram (ofc they tell the price AFTER the deal has been made).
oh and valeram doesnt have a dick or a vagina. they simply have a hole for pissing and a hole for pooping. for sexing Valeram literally rips their chest or stomach open and ejects a mass of guts and tentacles out of the wound and does the thing with them.
