The story features Twinborns, Metalborns who are able to use Allomancy and Feruchemy in conjunction, along with abilities from new metals not present in the original trilogy. "The Alloy of Law" is set in an analog to the early 20th century, on Scadrial, approximately 300 years after the conclusion of the original trilogy. It also introduces the concept of Twinborn, beings with one allomantic and one feruchemical ability, for the first time in the series. Lawman Waxillium Ladrian and his partner Lessie are investigating a serial killer in Feltrel, a small town in the Roughs. They decide to split up and Wax follows the murderer's tracks, leading him into a small church, where he finds that Lessie had been captured and held hostage by the serial killer. While trying to free her, Wax accidentally kills Lessie. Five months after the death of Lessie, Wax has given up the role as peacekeeper, and returned to Elendel, where after the death of his uncle and sister (who were involved in a carriage accident), he has become the head of his house. Due to his uncle's inadequate financial operations, Wax is trying to save House Ladrian from bankruptcy. The only way to do it is to find a suitable high-born lady from a financially stable house to marry. Just before meeting with promising prospect Lady Steris and her father, Wax is unexpectedly visited by his friend, deputy, and master of disguise Wayne (who is also a Twinborn with the abilities to create speed bubbles, and store health in his goldminds), who has come to Elendel to investigate a series of robberies and kidnappings for which a rogue band called "the Vanishers" is responsible. He wants Wax's help to solve the case. Although still torn between his previous life as a lawman and his obligations to House Ladrian, Wax declines to join him. During the meeting with Lady Steris, her father, and her half-sister Marasi (who is posing as a distant cousin to Lady Steris, for she is illegitimately born), Wayne pretends to be Wax's distant uncle.
