The Arm of Asheth is the guard detail assigned to the Temple of Asheth. They not only defend the temple and it grounds, they defend its cats and preistesses. They also guard The Living Asheth, and dispose of her once she has become too old to serve as the living form of that goddess. One of them killed Christopher Chant when he was trying to carry off Throgmorten, thus inadvertently allowing Christopher to drag a living creature from Series Ten to Series Twelve. They later show up at Chrestomanci Castle in an effort to recover the living Asheth. The goddess Asheth requires a life in order to spare the life of The Living Asheth, so Gabriel de Witt gives them one of his lives to placate the goddess Asheth.
