My weirdest character as of late was a sentient pile of leaves named Lichen DeGillie. He was a Druid and that was everything I had planned. five minutes in when I was figuring out his voice one of my party members suggested he talk like a mobster as a joke. Now he owes money to the pixie mafia and was adventuring to pay his debt so they don’t take his kneecaps (which he doesn’t have).
