As the title suggests, I’m looking for input as to how to incorporate Winter in a campaign taking place in an equatorial region of a world. I don’t see the rainy season being as much of a deterring factor for adventurers looking for loot, and summer replacing winter seems strange, as it’s damn hot at all times of the year.
I also don’t want to skip it, as that phase seems really fun.
Take “La Saga de los Confines” (traslated “Saga of the Borderlands” I think) novels where the husihuilke tribes cease their constant warring to trade one last time before the rainy season.
