A custom among the Laogunian elite is to save the bones of the deceased. Through surgery, portions of the bones are then implanted in the living relatives, enabling them to carry around a piece of their loved ones.
A common implantation point is the shoulder, and these memory limbs are a source of comfort for those mourning the loss of their loved ones. Due to the cost of the procedure, it is only common among the elite, who view it as a necessary part of the grieving process.
