A face is visible among the branches in this card's artwork; the face is missing its left eye, and is presumably intended to resemble the Odin.
In Greek mythology, the World Tree was under the ground and held Earth. Every day, it would be sawed by a type of goblins called Kallikantzaroi. When Christmas came, they would come to the surface to bring trouble to people. However, they forgot that the World Tree would heal itself. The Kallikantzaroi then must start over, sawing again until Christmas day.
