>>38518398Good question! I actually wrote about it a while ago!
https://rentry.org/vtwbg-vnuglore#seasonsBut the gist is that /vnug/ has about 3 seasons that can be considered winter
The first season starts around the time when the fiery leaves of deciduous trees fell off. Trees become either bare or under snow-covered pale leaves, exposing mosses, lichen, and mushroom that has been hidden by the greenery in the previous bright seasons. The forest has become quiet since the majority of birds have either migrated to warmer places or begun hiding from the cold, but some of the more cold-hardy animals (including the people) continue to hunt during this season, preying upon the fattened and less active animals preparing for hibernation. This is also the time of the wet freeze as the relatively warm temperature (25~40 degrees?) and increased rainfall invites stormy days of mixed rain and snow that could easily turn many places into mud bath.
The second season covers the time around the winter solstice. This is the time when the long snowy nights fully take hold of the land. Silent woods and whitened moors dominate the landscape, and some parts of the southern coast extend into the icy ocean. Almost all animals have retreated to the warm refuge of their home or dreams, and most humans spend their short days in shelters. The ground has mostly frozen solid, allowing reindeer herds to travel between sheltered spots to dig for lichen under the snow. This also means that this can be a season of war, since the dry weather and firm ground allow larger forces to traverse the terrain, and many less acclimatized foreigners will have a hard time functioning in the dark freezing cold.
The third season is when the day begins to lengthen and the air starts to melt once more. The first migratory birds return to their homeland and their songs herald the end of the dark seasons, and people begin emerging from their shelters to replenish their supplies of lumber and food, or ward off the boredom with outdoor activities like skiing. Reindeer herders start leading their herd to the frozen highlands to continue the lichen harvest away from the coming thaw seasons and swarms of mosquitoes.
