Pieces of toys for Santa's assembly factories were lost during shipping. Most of them were recovered, except for the winding keys, that ended up scattered all around.
Two elves were assigned to get in Discord's realm and recover them in servers all around the world. Borealis: the northern Santa's helper aprendice elf, and Australis: the southern slippery elf. They will pop in participating servers periodically, looking for them.
