The Hand of Fear

S14 E7: The fossilised hand has regenerated into a Kastrian called Eldrad who appears to be female, having modelled his form on Sarah Jane. He persuades the Doctor to take him back to Kastria, so that he might reclaim his heritage. When they arrive, they find Kastria dead. Its king has destroyed the race banks should Eldrad return. Eldrad is pierced by a spear when entering an elevator.
