Well, in my fictional universe there isn't a "Christmas" concept, so to speak... Yet, because I haven't planned that hahah!
But even so, in Menmar, winter can be a harsh season with or without snow, and Azoria doesn't exactly provide for the less fortunate; so, to emulate the Janni/Djinn people usually worship around the Realm of Rosham (or at least in the known areas I disclosed so far), Nadhine Anahita disguises herself and goes around distributing supplies for the people who live in the outer rings of the Imperial City, as if "granting wishes" for those who need the most.
Raheem, who's an actual Janni/Djinn, would definitely do some magical displays to lighten the spirits of every denizen of Azoria. Despite everything, the Imperial City is kind of growing on him xD
Esther would make jams and other canned goods to donate to the denizens of the less fortunate areas, whereas her husband Yami would do a good meal for her and his in-laws, and also offer his services as a repairman freely to ensure everyone would be sheltered in that time of year.
