This papercraft is the Jack of Blades' Mask (sometimes referred to as the Soul Mask), the grisly-looking and instantly recognizable mask worn by Jack of Blades, based on the action role-playing open world video game series Fable, the paper model was created by n8s.
The mask itself has the ability to trap and carry souls. Some speculate that Jack has used the mask to possess many Heroes over the centuries, granting him control of their body and making him appear immortal. This correlates with the fact that Jack's original physical form was broken long ago, through his fight with William Black.
After slaying Jack in his humanoid form, the Hero of Oakvale came into the possession of the mask. Jack's soul however, had escaped it, making it nothing more than an empty shell. Later, in order to open the Bronze Gate, the Hero uses the mask to trap the souls of three different types of Heroes - The Souls of Heroes quest. And after slaying Jack in his final form - a dragon - he traps Jack's soul, once again, in the mask. The Hero then has a choice of whether to wear the mask, or throw it into the volcanic surroundings of Archon's Folly. However, the plot explains that Hero refused to put the Mask on his face, and he threw it into lava. [Source: wikia]
