I’m in the early planning stages for an upcoming campaign. (Emphasis on early.) The main bad faction is the Wyld Hunt - a group of four fey warlords who will invade the realm and be the ultimate villains. In an effort not to retread certain tropes, I don’t want to reskin the four horsemen of the apocalypse. Instead, I want to name them after the four seasons in an attempt to have the players underestimate them - at first. When the party first hears of Lord Spring, I want them to think he’s a pushover and maybe even a good guy they can redeem. Then, when they finally meet Lord Spring, I want him to be terrifying. So I need negative expressions of the four seasons. Summer is easy: oppressive heat and drought. Winter is easy too: brutal cold. I could use some help with Spring and Autumn.
My current thought is that Srping causes Con saves against crippling allergies. Maybe torrential rain and flooding. But Autumn has me stumped. And I could always use more ideas for the other seasons.
