Aight I forget. Does Tristram have any kinda yuletide or whatever? Does Farah have a reason to wrestle Mal into a hideously festive and unfairly comfortable sweater.
Absolutely, Tristram has a mid-winter celebration. I haven't fleshed out the lore around it nearly as much as I did around the canon non-compliant damn it thanks Book of Adria Night of Souls, but it would share elements of real worldwide celebrations for the solstice. I would assume it takes place on or leading up to the winter solstice.
The more I think on it, and the Diablo realm's fixation on Light/Dark, it would probably be very candle and fire heavy, to help physically light the world when even the sun cannot.
(It would be fun if there were rune stones, like Stonehenge, where the sun's light on the solstice would illuminate the markings and create actual magic! For the summer as well.)
One thing this made me think of is Saint Lucy's Day. Lots of imagery around a martyr carrying the Light into the world. (I wonder just how much of this might carry over from Inarius' dealings in Sanctuary?)
I think there would be an avoidance of marriage/hand-fasting during this time, as there is a lot of imagery (at least in my fanon) around the Light for weddings and they would rather do that in the spring/summer/autumn.
Because Tristram's winters appear as though they would be cold, I assume eating/drinking/feasts would happen. Singing/carols seem to be a big part of a lot of solstice celebrations to help ward off evil, so yes, there would be that too.
I think gift-giving would also happen as a show of affection or love, though many of these gifts would likely be food or clothing.
I honestly can't think of a reason in Tristram that ugly sweaters would suddenly become a thing then and not the whole winter, but I could certainly see it in bigger cities like Westmarch where there would likely be more marketing around what the nobles are wearing.
However, I would like to personally believe that mortal!Auriel knits and crochets, and that from Archfall onward Mal is stuck wearing an absolutely gaudy shirt every single winter because she makes it for him as a present and he has zero excuses to not wear it.
