A pessimistic rock gnome tinkerer named Copper Knobberknocker (chaotic good rock gnome acolyte of Lathander), who begrudgingly helps with services and chores. The two argue incessantly. Copper walks around in a fuzzy suit and hood that he made himself; although it’s quite warm, it makes him look like a teddy bear.
If the characters talk to Copper, he tells them he’s worried about a friend named Macreadus, who is conducting research at an old cabin in the wilderness (see “Black Cabin”). He says that if the characters find themselves nearby, he would appreciate it if they looked in on Macreadus, who’s trying to build a device that could end the Frostmaiden’s eternal winter and return summer to Icewind Dale.
